A race car starts from rest on a circular track of radius 310 m. Its speed increases at the constant rate of 0.6 m/s 2 . At the

point where the magnitudes of the radial and tangential accelerations are equal, determine the speed of the race car. Answer in units of m/s

Answer:

The speed of the race car is 13.63 m/s.

Explanation:

It is given that,

Radius of the circular track, r = 310 m

Acceleration of the car, v = 0.6\ m/s^2

We need to find the speed of the race car. In circular motion, the object moves under the action of centripetal acceleration which is given by :

a=\dfrac{v^2}{r}

v=\sqrt{a\times r}

v=\sqrt{0.6\times 310}

v = 13.63 m/s

So, the speed of the race car is 13.63 m/s. Hence, this is the required solution.

The electric motor of a model train accelerates the train from rest to 0.620 m/s in 21ms. The total mass of the train is 825 g.
Rudiy27

Explanation:

Average power = change in energy / change in time

P = ΔE / Δt

P = (½ mv²) / t

P = (½ (0.825 kg) (0.620 m/s)²) / (0.021 s)

P = 7.55 Watts
