Question

A baseball player throws a ball into the air with an initial velocity of 22 m/s [up].

a) How high up does the ball go?

b) If she catches the ball from the same height that she threw it, how long was the ball in the air?

Answer 1

Initial Velocity, u = 22 m/s

Final Velocity, v = 0 m/s

Acceleration due to gravity, g = - 9.8 m/s2 ( beacuse it is moving upwards )

a)

Using equation of Motion :

Height reached,

b)

Using equation of Motion :

Time taken to reached maximum height,

Time for which the ball was in the air,
