Define free fall and solve problems involving free fall motion
In each case shown, someone is running on a flatbed train car as the train moves. In cases C and D, the person is running toward the front of the train, while in cases A and B the person is running toward the rear. The speeds of the train and of each person relative to the train are given.
Rank the speed of the runners relative to the observer standing beside the tracks.

Shown below are the paths two motorcyclists took on an afternoon ride. Both started at the same place, and both took the same time for the ride. Rider A traveled east for 19 km and then south for 4 km. Rider B traveled south for 7 km and then east for 16 km.
Is the magnitude of the displacement of the rider (i) greater in case A, (ii) greater in case B, or (iii) the same in both cases? Explain your reasoning.

Target: time between photogates = 0.12 s
The figure above shows a cart on an inclined ramp. The cart is released from rest a distance from photogate 1. You are tasked to determine the distance from photogate 1, , to put a second photogate, so that the time it takes for the cart to travel between the two gates is .
How far from photogate 1 should photogate 2 be placed to get 0.12 s between gates?
Use the constant-acceleration particle model to:

Determine whether the coefficient of restitution, , for a specific ball remains constant when dropped from various heights. Do this by comparing drop height to bounce height for your assigned ball.
Title and objective of the experiment:
Theoretical background:
Hypotheses:
Is the coefficient of restitution constant for your ball? Do this by comparing drop height to bounce height for your assigned ball.
The coefficient of restitution (symbol: ) is a dimensionless quantity that describes how much energy is conserved in a collision, specifically how well an object bounces back after impact. It is used to characterize the elasticity of collisions between two bodies.
