Question 1

Part 1

A Knight of Round Table fires off a vat of burning pitch from his catapult at 15.2 m/s, at 34 above horizontal. The acceleration of gravity is 9.8 m/s2 .How long is it in the air? Answer in units of s

Part 2
what is the horizontal component of velocity? Answer in units of m/s

Part 3
How far from a catapult does it land? Answer in units of m

Question 2

A long jumper leaves the ground at an angle of 15.8 to the horizontal and at a speed of 10.8 m/s. How far does he jump? The acceleration because of gravity is 9.8 m/s2 .Answer in units of m.

Question 3

To win game, a place kicker must kick a football from a point 25 m (27.34 yd) from the goal, and the ball must clear the crossbar,which is 3.05 m high. When kicked, ball leaves the ground with a speed of 17 m/s at an angle of 48.5 from the horizontal. The acceleration of gravity is 9.8 m/s2.

By how much a vertical distance does the ball clear the crossbar? Answer in units of m
