A car is traveling at a speed of 54 km/h. Breaks are applied so as to produce a uniform acceleration of -0.5 m/s2. Find how far the car will go before it is brought to rest
Explanation:
u=54 km/h
54*5/18=15 m/s
v=0m/s
t=?
acceleration=-0.5m/s^2
we know that a=v-u/t
so,
t=v-u/a
t=15-0/0.5
=15/0.5
=30
therefore, the time is 30 second

Water flows into a swimming pool at the rate
of 5.25 gal/min.
If the pool dimensions are 33.8 ft wide, 40 ft
long and 11.1 ft deep, how long does it take to
fill the pool? (1 gallon = 231 cubic inches)
Answer in units of min.
...
148.49 minutes
First find the cubic inch area of the pool.
33.8 x 40 x 11.1
You get 15007.2
Convert that to inches by multiplying it by 12.
You get 180086.4. Divide that by 231 since each 1 gallon is 231 cubic inches.
You get 779.594805
Now divde that by 5.25 (rate of flow)
You get 148.49 rouned to the nearest hundreth.
If you are able to do brainliest, I'll be happy. This took some big division...
A ball is thrown horizontally from a height of 1 m and lands 5 m away. What is the time of flight of the ball?
Answer:
The time of flight of the ball is approximately 0.4515 s
Explanation:
The given information are;
The vertical height, s = 1 m
The horizontal distance travelled, x = 5 m
The direction of the initial velocity = Horizontal
Given that the vertical height is known and the ball is in free fall, the time of flight, t, will depend on the vertical motion of the ball
The equation of motion of the ball can be presented as follows;
s = u·t + 1/2·g·t²
The initial vertical velocity = 0
∴ 1 = 1/2 × 9.81 × t²
t² = 1/(1/2 × 9.81 ) ≈ 0.20387 s²
t = √0.20387 = 0.4515 s
The time of flight of the ball ≈ 0.4515 s.

Answer:
25 minutes
Explanation:
A dog walks 40. m west, then 10. m east and then 50. m south. What is the
distance and displacement traveled?
The total distance traveled by the dog is 100 m and the displacement of the dog is 58.31 m.
The given parameters;
Initial position of the dog, 40 m westSecond position of the dog, 10 m eastFinal position of the dog, = 50 southThe displacement of the dog is the change in its initial position and the final position.
The resultant of the dogs position in x-direction: = 40 m - 10 m = 30 m
The resultant of the dogs position in y-direction: 50 m
The magnitude of the displacement;
R² = 30² + 50²
R² = 3400
R = √3400
R = 58.3 m
The distance covered by the dog is the sum of all the positions of the dog.
Distance = 40 m + 10 m + 50 m
Distance = 100 m.
Thus, the total distance traveled by the dog is 100 m and the displacement of the dog is 58.31 m.

A golfer pulls on the eighteenth green at a distance of 5.0m from the hole. The ball rolls straight. In the positive direction, but overshoots the hole by 1.2m. The golfer then putts back to the hole and sinks the putt for par. What is the displacement of the ball?
Answer:
Explanation:
The initial position of the ball = - 5 .0 m from the hole .
It is negative because , direction towards the hole is positive so direction from the hole will be negative .
Final position of the ball = 0 m from the hole .
Displacement of the ball = Final position - Initial position
= 0 - ( - 5 ) = 5 .0 m
Displacement = + 5 m

Cindy runs 2 kilometers every morning. She takes 2 minutes for the first 250 meters, 4 minutes for the next 1,000 meters, 1 minute for the next 350 meters, and 3 minutes for the rest.
Cindy’s average speed for the entire run is meters per minute. One kilometer is the same as 1,000 meters.
Answer:
200 m/min.
Explanation:
From the question given, we obtained the following data:
Total distance = 2 km
Total time = 2 + 4 + 1 + 3
Total time = 10 mins
Average speed =.?
Next, we shall convert 2 km to metre (m). This can be obtained as follow:
1 km = 1000 m
Therefore,
2 km = 2 km × 1000 m / 1 km
2 km = 2000 m
Therefore, 2 km is equivalent to 2000 m.
Finally, we shall determine the average speed of Cindy as follow:
Total distance = 2000 m
Total time = 10 mins
Average speed =.?
Average speed = Total distance /total time
Average speed = 2000 /10
Average speed = 200 m/min.
Therefore, the average speed of Cindy is 200 m/min.

- Approximately what are the coordinates of the Hawaii Hot
Spot?
(1) 50 N, 120 W
(3) 25 N, 158 W
(2) 25 N, 158 €
(4) 25 S, 158 E
Answer: (3) 25°N, 158°W
Explanation:
The Hawaii Hotspot is one of the most popular on the planet and is the reason the Hawaii islands were created as it created volcanoes under the Hawaii islands that erupted as the Pacific plate moved over them and then the lava cooled thereby forming the different Hawaii islands.
The approximate location of the hotspot is 25°N, 158°W in the pacific ocean.
Base your answer to this question on the information below and on your knowledge of physics.
A wave traveling through a uniform medium has an amplitude of 0.20 meter, a wavelength of 0.40 meter, and a frequency of 10 hertz.
Determine the period of this wave.
What’s the period of this wave ?
Answer:
T=1/f
= 1/10
= 0.1 s
v = wavelength × frequency
= 0.40m × 10 Hz
= 4ms^-1
T = wavelength / velocity
= 0.04m / 4 ms^-1
= 0.1 m
Explanation:
so first i used the formula T=1/f and i found that the period, T is 0.1s
and secondly , to check whether i got the correct answer , i used a different formula
i used the formula T = wavelength / velocity
but there's an unknown in it , that's the velocity
so to find the velocity , i used the formula v = wavelength × frequency
when i've done the calculation , the second value of T is same as the first value of T
so , the value of the period, T is 0.1s
How would you determine the acceleration from a v vs. t graph?
The acceleration is the slope of the v/t graph.
-- If the graph is a straight line, then pick any piece of the line, or even the whole graph, and divide (change in 'y') by (change in 'x') for the piece you chose.
-- If the graph is a curve or a squiggle, then you can do the same thing with a piece of it, and you get the average acceleration during that piece.
-- If you need the acceleration at one point on the graph, you have to lay a straight line against that point on the graph, and find the slope of that straight line.
