A 2300-kg car slows down at a rate of 3.0 m/s2 when approaching a stop sign. What is the magnitude of the net force causing it to slow down?

Answers

The magnitude of the net force causing the 2300kg car to slow down is 6900N

HOW TO CALCULATE FORCE:

The net force applied on a moving object can be calculated by multiplying the mass of the object by its acceleration. That is;

Force (N) = mass (kg) × acceleration (m/s²)

According to this question, a 2300-kg car slows down at a rate of 3.0 m/s2 when approaching a stop sign. The net force causing the car to stop can be calculated as follows:

F = 2300kg × 3m/s²

F = 6900N

Therefore, the magnitude of the net force causing the 2300kg car to slow down is 6900N.

why are hydraulic brakes less effective if there is air in the liquid

Answers

Answer:

air is compress able

since air can be compressed, then the hydraulics will not work as well. It won't be able to push the object or brake the wheels. Since water cannot be compressed, it is able to push something, that's how hydraulics work.

Explanation:

it reduces pressure and essentially makes the process less effective.

1) how can you show that atmospheric exerts pressure?
2) how do you measure the volume of an irregular solid ? explain an experiment with diagram.​

Answers

Answer:

1. While boiling replace the cap and allow it to cool. Vapours inside condense and form water creating vacuum above them. Observation - The can crumbles due to air pressure from outside. This proves that air exerts pressure.

2. Measure the volume of the liquid displaced when the object is submerged. Measure the initial volume of water in graduated cylinder. Submerge the irregular object. Measure the final volume of the water.

— The difference between the initial volume and the final volume is the volume of the object.

A ship left the dock and travelled north at 50km/hr for 2 hours then it turned west at 60km/hr for 3 hours. What is the net resultant displacement vector R

Answers

Answer:

resultant displacement = 20√1o6 km = 205912.6 m in the direction of western north.

Explanation:

assume that the ship started moving from A to B (north at 50km/hr for 2 hours) so the covered distance will be: 50*2 = 100 km

then it moves from B to C so the covered distance will be: 3*60 = 180 km

using Pythagoras, we get the resultant displacement = 20√1o6 km = 205912.6 m in the direction of western north.

The transformation function of the given exponential function is -1/4, -1, -4, -16, -64. Hence option D is correct.

What is an exponential function?

An exponential function is a mathematical relation to find exponential growth or decay for the given data. It represents the constant change in independent variables and gives the same proportional change.

The exponential function is expressed as f(x) = exp (x) or eˣ where x is variable and e is constant which is called the base of the equation.  

From the given,

the exponential function f(x) = 1/4, 1,4,16,64

The transformation function G(x) is the inverse of the exponential function and is equal to -1/4,-1, -4,-16,-64.

Hence, the ideal solution is option D.

Wile E. Coyote is holding a "HEAVY DUTY ACME™ ANVIL" on a cliff that is 40.0 meters high. The Roadrunner (beep-beep), who is 1.0 meter tall, is running on a road toward the cliff at a constant velocity of 10.0 m/s. Wile E. Coyote wants to drop the anvil on the Roadrunner's head. How far away should the Roadrunner be when Wile E. drops the anvil?​

Answers

Answer:

53.8

Explanation: I plugged it on the formula

Coyote should drop the anvil when the Roadrunner is 20.3 meters away from the cliff.

What is velocity?

The velocity of the object is defined as the fraction of the displacement of the object over a period of time.

We can solve this problem by finding the time it takes for the anvil to fall from the cliff to the ground, and then using that time to find how far the Roadrunner has travelled during that time.

First, we need to find the time it takes for the anvil to fall from the cliff. We can use the equation:

d = 1/2 x  g  x t²

where d is the distance (40.0 meters), g is the acceleration due to gravity (9.81 m/s^2), and t is the time.

Solving for t, we get:

t = √(2d/g)

t = √(2 x 40.0/9.81)

t = 2.03 seconds

So it takes 2.03 seconds for the anvil to fall from the cliff to the ground.

During this time, the Roadrunner has travelled a distance equal to its velocity multiplied by the time:

distance = velocity x  time

distance = 10.0 m/s x 2.03 s

distance = 20.3 meters

Therefore, Wile E. Coyote should drop the anvil when the Roadrunner is 20.3 meters away from the cliff.
