A shotput 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?
