Construct the displacement graph for the subway shuttle train as shown in Figure 2.18(a). Your graph should show the position of the train, in kilometers, from t = 0 to 20 s. You will need to use the information on acceleration and velocity given in the examples for this figure.

Tennis Ball Dropped onto a Hard Floor| Falling Objects| Kinematics| College Physics| Problem 2.58

A soft tennis ball is dropped onto a hard floor from a height of 1.50 m and rebounds to a height of 1.10 m. (a) Calculate its velocity just before it strikes the floor. (b) Calculate its velocity just after it leaves the floor on its way back up. (c) Calculate its acceleration during contact with the floor if that contact lasts 3.50 ms (0.0035 s). (d) How much did the ball compress during its collision with the floor, assuming the floor is absolutely rigid?

Coin Dropped From a Hot-Air Balloon| Falling Objects| Kinematics| College Physics| Problem 2.57

A coin is dropped from a hot-air balloon that is 300 m above the ground and rising at 10.0 m/s upward. For the coin, find (a) the maximum height reached, (b) its position and velocity 4.00 s after being released, and (c) the time before it hits the ground.

Falling Objects| Kinematics| Steel Ball Dropped onto a Hard Floor| College Physics| Problem 2.56

A steel ball is dropped onto a hard floor from a height of 1.50 m and rebounds to a height of 1.45 m. (a) Calculate its velocity just before it strikes the floor. (b) Calculate its velocity just after it leaves the floor on its way back up. (c) Calculate its acceleration during contact with the floor if that contact lasts 0.0800 ms (d) How much did the ball compress during its collision with the floor, assuming the floor is absolutely rigid? 

Falling Objects| Kinematics| Rock Dropped into a Dark Well| College Physics| Problem 2.55

Suppose you drop a rock into a dark well and, using precision equipment, you measure the time for the sound of a splash to return. (a) Neglecting the time required for sound to travel up the well, calculate the distance to the water if the sound returns in 2.0000 s. (b) Now calculate the distance taking into account the time for sound to travel up the well. The speed of sound is 332.00 m/s in this well.
