Question

A batted baseball leaves the bat with an angle of 30* above the horizontal is caught by an outfielder 120 m from the plate.
a. What was the initial velocity of the ball?
b. How high did it rise?
c. How long wasit in the air?

Answer 1

(a) to find v, use the range v^2/2g sin2θ = 120
(b) h = v^2/2g sin^2 θ
(c) v-gt = 0 gives the rise time. Double that to find total flight time
