Answer:

Approximately [tex]21.6\; {\rm m\cdot s^{-1}}[/tex], assuming that the coefficient of kinetic friction between the tires and the ground stays the same.

Explanation:

Let [tex]\mu_{k}[/tex] denote the coefficient of kinetic friction between the tires and the ground.

Let [tex]m[/tex] denote the mass of the truck. Let [tex]g[/tex] denote the gravitational field strength. The weight of this truck would be [tex]m\, g[/tex]. Since the curve is flat, the magnitude of the normal force [tex]F_\text{normal}[/tex] between the truck and the ground would also be [tex]m\, g\![/tex].

Let [tex]v = 32.5\; {\rm m\cdot s^{-1}}[/tex] denote the speed at which the truck goes around the curve with a radius of [tex]150\; {\rm m}[/tex]. The (horizontal) centripetal acceleration of the truck would be:

[tex]\displaystyle a = \frac{v^{2}}{r}[/tex].

The horizontal net force on the truck (of mass [tex]m[/tex]) would need to be exactly:

[tex]\displaystyle F_\text{net} = m\, a = \frac{m\, v^{2}}{r}[/tex].

The friction between the tires of the truck and the ground is the only horizontal force on the truck. Thus, this friction would need to supply the entirety of this horizontal net force:

[tex]\displaystyle F_\text{friction} = F_\text{net} = \frac{m\, v^{2}}{r}[/tex].

Notice that increasing [tex]v[/tex] would require an increase in the kinetic friction between the truck, [tex]F_\text{friction}[/tex]. However, since [tex]F_\text{friction}\![/tex] is at most [tex]\mu_{k}\, F_\text{normal}[/tex] (which is equal to [tex]\mu_{k}\, m\, g[/tex]):

[tex]\begin{aligned}\frac{m\, v^{2}}{r} &= F_\text{friction} \\ & \le \mu_{k}\, F_\text{normal} \\ &= \mu_{k}\, m\, g\end{aligned}[/tex].

Therefore, when the radius of the curve is [tex]r^{\prime}[/tex], the maximum velocity of this truck would be:

[tex]\begin{aligned}v^{\prime} &= \sqrt{\mu_{k}\, g\, r^{\prime}}\end{aligned}[/tex].

Likewise, it is possible to express [tex]\mu_{k}[/tex] in terms of [tex]r[/tex], [tex]g[/tex], and max speed [tex]v[/tex]:

[tex]\displaystyle \mu_{k} = \frac{v^{2}}{r\, g}[/tex].

Substitute this expression for [tex]\mu_{k}[/tex] back into the expression for [tex]v^{\prime}[/tex]:

[tex]\begin{aligned}v^{\prime} &= \sqrt{\mu_{k}\, g\, r^{\prime}} \\ &= \sqrt{\frac{v^{2}}{r\, g}\, g\, r^{\prime}} \\ &= \sqrt{v^{2}\, \frac{r^{\prime}}{r}}\end{aligned}[/tex].

Given that [tex]v = 32.5\; {\rm m\cdot s^{-1}}[/tex], [tex]r = 150\; {\rm m}[/tex], and [tex]r^{\prime} = 66.0\; {\rm m}[/tex]:

[tex]\begin{aligned}v^{\prime} &= \sqrt{v^{2}\, \frac{r^{\prime}}{r}} \\ &= \sqrt{(32.5\; {\rm m\cdot s^{-1}})^{2} \times \frac{66.0\; {\rm m}}{150\; {\rm m}}} \\ &\approx 21.6\; {\rm m\cdot s^{-1}}\end{aligned}[/tex].

Answer:

Most light sources can be classified into three main types: continuous, absorption, and emission. A hot, opaque object, like the filament in an incandescent light bulb, emits a continuous spectrum, having light of all wavelengths. A hot, dense gas is another example of an object that emits a continuous spectrum.

"Hecto" prefix is given when a physical quantity generally 100 times the amount of the unit.

Based on the calculations, the acceleration of this wagon along the ground is equal to: D. 3.60 m/s².

Given the following data:

Mass = 10 kg.

Angle = 35°

Force = 44 Newton.

In accordance with Newton's Second Law of Motion, the net force acting on this wagon is equal to the horizontal component of the force that is parallel to the slope:

F = macosθ

Substituting the given parameters into the formula, we have;

44 = 10 × a × cos35

44 = 10a × 0.8192

44 = 8.192a

a = 44/8.192

a = 3.60 m/s²

Answer:

240.1 m

Explanation:

Potential energy  ( mgh)  is fully converted to Kintetic energy ( 1/2 mv^2)

  equate them

mgh = 1/2 mv^2     divide by 'm'

gh = 1/2 v^2

9.8 h = 1/2 v^2

(a) The mass of the car is 1,795.92 kg

(b) The initial momentum of the car is 44,897.96 kgm/s.

(c) the change in momentum for the car is 44,897.96 kgm/s..

(d) The time it takes the braking force to bring the car to rest is 69.4 s.

The mass of the car is calculated as follows;

W = mg

m = W/g

m = (17,600)/9.8

m = 1,795.92 kg

Pi = mvi

Pi = 1,795.92 x 25

Pi = 44,897.96 kgm/s

ΔP = Pf - Pi

ΔP = 0(1,795.92) - 44,897.96 kgm/s

ΔP =  - 44,897.96 kgm/s

F = ma

-650 = 1,795.92(a)

a = -650/1,795.92

a = -0.36 m/s²

Answer:

Explanation:

The electrostatic force between these electrons will be 2.3×10⁻²⁰ N.

The force of attraction between two charges, according to Coulomb's law, is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Charges that are similar repel each other, whereas charges that are diametrically opposed attract each other.

They will repel, moving in opposite directions at the same speed. Because the magnitude and nature of the charge are same.

The electrostatic force between these electrons is;

[tex]\rm F= \frac{Kq_1q_2}{r^2} \\\\ F=\frac{9 \times 10^9 \times -1.6 \times 10^{-19} \times- 1.6 \times 10^{-19} }{(0.10 \times 10^-3)^2} \\\\F= 2.3 \times 10^{-20} \ N[/tex]
