Question

a.)A ball isthrown vertically upwards with an initial velocity of 27.0 m/s.Neglecting air resistance, how long is the ball in the air?

b.)What is the greatest height reached by theball?

c.)Calculate the first time where the ball hashalf of its initial velocity.

c.)Calculate the first time where the ball hashalf of its initial velocity.

Explanation / Answer

Given : Initial velocity ( u ) = 27 m/s     g = 9.8 m/s2    time ( t ) = u / g                 = (27 m/s) / (9.8 m/s2 )                 = ------ s    Height ( h ) = u2 / 2 g                      = ------ m Solve it I hope it helps you    time ( t ) = u / g                 = (27 m/s) / (9.8 m/s2 )                 = ------ s    Height ( h ) = u2 / 2 g                      = ------ m Solve it I hope it helps you
