Question: A 0.30-kg block is placed in a straight gutter that allows the block to move only along the gutter. The friction between the gutter walls

A 0.30-kg block is placed in a straight gutter that allows the block to move only along the gutter. The friction between the gutter walls and the block is negligible. You are exerting a constant force of 4.5 N on the block at an angle of 60 with respect to the gutter (Figure 1). The block is initially at rest. Assume the block has moved 20 cm
