Chapter 3.1, Problem 1aT
A block is moving to the left on a frictionless, horizontal table. A hand exerts a constant horizontal force on the block.
1. Suppose that the work done on the arrows at right to show the direction of the displacement of the block and thedirection of the force by the hand.
Explain how you chose the direction of the force on the block by the hand.
Is the block speeding up, slowing down, or moving with constant speed? Explain.
2. Suppose that the block again moves to the left but now the work done by the hand is negative. In the space at right,draw arrows to represent the direction of the displacement of the block and the direction of the force by the hand.
Explain how you chose the direction of the force on the block by the hand.
Is the block speeding up, slowing down, or moving with constant speed? Explain.
