Find the speed of the ball just before it strikes the ground

Reference no: EM13285995

A ball is thrown from the top of a building upward at an angle of 46 degrees to the horizontal and with an initial speed of 30m/s. The ball is thrown at a height of 44m above the ground.

(a) How long is the ball in flight? The acceleration due to gravity is 9.8m/s^2. Answer in units of s.

(b) What is the speed of the ball just before it strikes the ground? Answer in units of m/s.
