Question

A body is projected horizontally from top of tower of height 80 m with speed 30m/s then find the velocity and angle at which it hits the ground. ​

Answer 1

Answer:

As the acceleration due to gravity is vertical so the horizontal component Vx=30m/s will remain constant.

and the vertical component will get increased from 0 to v given by 2gh=2×10×80=40m/s

so the net velocity will be V=v2+vx2=1600+900=50m/s
