From Kinematics

A girl throws a ball vertically upwards with speed 8ms from a window which is 6m above horizontal ground.

(a)find the greatest height above the ground reached by the ball.

1.5s later she drops a second ball from rest out of the same window.

(b) Find the distance below the window of the point where the balls meet

anser of (a) and (b) are 9.27 and 0.104 respectively


Part (a) and (b)

For the second part I found the flight time... there may be a shorter method..

cheers m8 thats kind of the method i chose except my answer seemed to lean towards 0.2014

i expect there is an easier way but this method is good. Cheers again.
