Question

A person watching through the window of an apartment sees a ball
that rises vertically up then vertically down for a total time of 0
5 sec If the height of the window is 2m find maximum height above
the window reached by the ball?(g=10 m/s^2)

Awesome Asim · Answer

hey santosh,
s=ut+1/2at2
taking the heighest point as the start of the motion, u = 0 and
t = 0 5/2 s is the max height reached
= s = 0[(0 5)/2] + 1/2(-10)[(0 5/2)2]
= s = 0 - 2 5/8 = 0 3125
