Worksheet 2: Compare falling objects

1. A yellow ceramic ball is dropped (from rest) from a height of 1.5 meters and hits a landing pad.Analyze this situation. Start by deciding what models apply and why, then draw many diagrams to represent the situation, then solve for as many unknowns as you can.

2. An aluminum ball is dropped (from rest) from a height of 1.5 meters and hits a landing pad.

3. A ping-pong ball is dropped (from rest) from a height of 1.5 meters and hits a landing pad.



4. A yellow ceramic ball moving at 3 m/s rolls off of a horizontal table, falls 1.5 meters, and hits a landing pad.

5. A yellow ceramic ball is launched from the edge of a 1.5 meter table. The initial velocity of the ball is 3 m/s at 20º.

Rank the above situations from greatest to least based on the time for the sphere to hit the ground. Make your ranking in one single line, using only the > and = signs. Ties are possible.

Explain the reasons behind your ranking. Try to give a brief explanation that covers all the cases rather than explain each case individually.

Rank the situations from greatest to least based on the horizontal distance of the sphere from the edge of the table at the time it hits the floor. Make your ranking in one single line, using only the > and = signs. Ties are possible.

Worksheet 3: Projectile Practice

6. The movie "The Gods Must Be Crazy" begins with a pilot dropping a bottle out of an airplane. It is recovered by a surprised native below, who thinks it is a message from the gods. If the plane from which the bottle was dropped was flying at a height of 500 m, and the bottle lands 400 m horizontally from the initial dropping point, how fast was the plane flying when the bottle was released?

7. Emanuel Zacchini, the famous human cannonball of the Ringling Bros. And Barnum & Bailey Circus, was fired out of a cannon with a speed of 24 m/s at an angle of 40º to the horizontal. If he landed in a net 56.6 m away at the same height from which he was fired, how long was Zacchini in the air?

8. Jack be nimble, Jack be quick, Jack jumped over the candlestick with a velocity of 5 m/s at an angle of 30º to the horizontal. Did Jack burn his feet on the 0.25-m high candle?



9. A student throws his worthless lab partner off of a 120 m high bridge with an initial downward speed of 10 m/s.a. How long does it take the deadbeat to hit the ground below?b. How fast is he going at the moment of impact?

10. Throckmorton drops his bowling ball out the car window 1.0 m above the ground while traveling down the road at 18 m/s. How far, horizontally, from the initial dropping point will the ball hit the ground? If the car continues to travel at the same speed, where will the car be in relation to the ball when it lands?

11. Len is running to school and leaping over puddles as he goes. From the edge of a 1.5-m long puddle, Len jumps 0.2 m high off the ground with a horizontal velocity component of 3 m/s in an attempt to clear it. Determine whether or not Len sits in school all day with wet socks on.
