At the same moment, one rock is thrown upward at 4.5 m/s and another thrown downward at 3.4 m/s. what is the relative velocity of the first rock from the perspective of the second rock? assume that up is positive.

The man fires an 80 g arrow so that it is moving at 80 m/s when it hits and embeds in a 8.0 kg block resting on ice. how far will the block slide on the ice before stopping? a 7.1 n friction force opposes its motion.

This question is worth 54 points ! rock falls from a ledge to the ground what energy conversion occurs during this process a potential to kinetic b kinetic to potential c thermal to mechanical d chemical to mechanical
