QUESTION:
If F = (10 s) N, where s is in meters, and the contact surface between the block and the ground is smooth, determine the power of force F when s = 5 m. When s = 0, the 20-kg block is moving at v = 1 m/s.

QUESTION:
If F = (10 s) N, where s is in meters, and the contact surface between the block and the ground is smooth, determine the power of force F when s = 5 m. When s = 0, the 20-kg block is moving at v = 1 m/s.
ANSWER:
Step 1 of 2
Calculate the force
Substitute
Here frictional force is zero because the surface is smooth .
