A ball is launched with an initial velocity of 22.6 m/s at a 45°angle from the top of a cliffthat is 11.0 m above the water below.Useg = 10 m/s2 to simplify the calculations. Note:youcould answer these questions using projectile motion methods,buttry using an energy conservation approach instead.
(a) What is the ballâs speed when it hits the water?
1 m/s
(b) What is the ballâs speed when it reaches itsmaximumheight?
2 m/s
(c) What is the maximum height (measured from the water)reachedby the ball in its flight?
3 m
