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
1 answer:
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, 
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 :



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

Explanation:
because 50.0/10.0 = 5.0
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
