Two bullets are fired with horizontal velocities of 50m/s and 100 m/s from two guns at a height of 19.6 m .(a) after how much time and which bullet will strike first ?(b)what would be the path of the bullets?(g=9.8m/s^2₎

Solution

a)Both bullets strikes ground at same time
REASON::
As there is no vertical components of velocities for both bullets , it is to be taken as freely falling condition for calculating height of the tower and also for the time.
Time taken to fall/ touches ground
t^2=2×g×h
t^2=2×9.8×19.6
t^2=2×9.8×2×9.8
t =2×9.8
t=19.6 seconds.

b)The bullet follows a parabolic path
