1)If a bullet from a gun is shot horizontally at 500 mph (223.5 m/s), how far does it drop after 100 meters?

Answer:Dy = - .98 m

 

2) In the movie “The Gods must be Crazy”, it 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 an altitude of 500 m, and the bottle lands 400m horizontally from the initial dropping point, how fast was the plane flying when the bottle was released?

Answer: Vx =39.6 m/s

 

3) If I toss a marble into the air at a velocity of 3.9 m/s at an angle of 50 degrees, and it reaches the same height 0.6097 seconds later, how far did it travel horizontally?

Answer: Dx=1.528 m

 

4) Jack be nimble, Jack be quick, Jack jumped over the candlestick with a velocity of 5 m/s at an angle of 30 degrees. Did Jack burn his feet on the  0.25 m high candle?

Answer: Dy = .319 m, no!

 

5) RANGE: How far away from a target, level with you, do you have to stand to hit it, throwing a ball at 25 m/s at a 30 degree angle?

Answer: Dx=55.23 m

 

 

 

6) Minnie jumps up off a 14 meter high cliff at a 20 degree angle with a speed of 5 m/s. Mickey is at the bottom of the cliff, 55 meters away from the bottom. He starts running when she jumps . How long does it take Minnie to reach the bottom? How fast should Mickey run to catch her?

Answer: T=1.87 sec, Vmickey=29.411 m/s
