Explanation:
the force exerted from by the car on the wall Is contact force
the force exerted by the wall on the car i don't know
Answer:
The average power is 15.26 W.
Explanation:
Given that,
Force = 29 N
Radius = 0.27 m
Time = 1.9 s
We need to calculate the power
Using formula of power
Here,
Where, F = force
t = time
r = radius
Put the value into the formula
Hence, The average power is 15.26 W.
