1. Part of the drawing below is a sketch of the velocity vs. time plot of the motion of an object. What do you think are the appropriate sketches for its displacement and its acceleration? Draw them the blank sketches provided.
2. You have a tiny slip of paper and a large rectangular wooden block. If you put both of them side-by-side and drop the two to the floor from the same height, the block gets to the floor first. Can you think of (and describe) three "simple" ways (using nothing, absolutely nothing, but the two objects, and not in special rooms, with wind, with fancy equipment, etc.) to ensure that the two objects will fall to the floor in the same time?
3. There exists a theory that shorter basketball players have an "inbuilt" advantage in converting free throws; it is an easier process for them to be successful. Test theory out by playing with Fendt's Projectile demo as applied to two WNBA players. Here are the dimensions that you must use:
The distance from the free throw line where the player stands to where the floor is directly below the center of the hoop is 4.50 m
The hoop is set at a height of 3.05 m
The hoop's diameter is 0.48 m
The ball's diameter is 0.24 m
Taller player
Typically, will launch the ball from a height of 2.2 m from the ground
Shorter player
Typically, will launch the ball from a height of 1.6 m
By playing with the angle of launch and the speed of launch, how can you find enough "evidence" to convince someone that, all other things being equal, the physics of projectile motion either support the theory convincingly or little at all.
Give your answer in the form of the data you collected from playing the demo, explaining in detail how you went about collecting them.
