Following your push the ball rolls down the lane at 4.2m/s. What is the net force on the ball as it rolls down the lane at the constant speed?
Answer:
a).11.546J
b).2.957kW
Explanation:
Using Inertia and tangential velocity
a).


Now using Inertia an w

average power=
b).
power=t*w
P=
P=2.957 kW
Rate of speed (3 m/s north is three miles per second north, so it's a rate of speed)
The correct answer would be 1.375 < t < 3 i hope this helps anyone
