I 3. A 68 kg ice skater moves to the right with an initial velocity of 2.9 m/s. Her 115 kg
partner is moving in the opposite direction at 1.3 m/s. What will be the final velocity of the pair if
they grab onto each other in a graceful embrace?

In this experiment, you will use a track, a toy car, and some washers to explore newton’s first two laws of motion. you will make observations and collect data regarding the motion of these objects. in the space below, write a general scientific question that you will answer by doing this experiment.

A500g object falls off a cliff and losers 100 j from its gravitational potential energy store. if the gravitational field strength g=9.8n/kg, how high is the cliff?

Acrow drops a 0.11kg clam onto a rocky beach from a height of 9.8m. what is the kinetic energy of the clam when it is 5.0m above the ground? what is its speed at that point?
