A shot put thrower releases the shot with a release speed of 15m/s and a release angle of 42° above the horizontal. The initial height that the thrower releases the shot is 2 m. In all the problems, neglect the effect of air resistance.

1.

What is the maximum height reached by the shot (relative to the ground)?

2.

How long is the shot in the air for?

3.

How far doe

s the shot travel

horizontally?

4.

What is the vertical velocity just before the shot lands on the ground?

5.

If you were to coach this shotput thrower, would you advise him to throw at a 45° release

angle to increase his distance? Why or why not?
