Question

Will the velocity of the book change as it moves across the surface with NO friction? Explain your answer.

Answer 1

Explanation:

If we push on the book with a force of less than 5 N, the book won't move, because the frictional force will exactly balance the force we apply. If we push with a 1 N force, a 1 N frictional force opposes us.

Answer 2

As mass is constant during free-weight resistance training, a greater impulse will result in a greater velocity.Explanation:
