Question

Discuss the motion of a body when projected horizontally from a height ​

Answer 1

A body reaches the ground with the velocity of  at time .

Explanation:

Given that,

Height = h

Projection velocity =u

(I). We need to calculate the time it will take to reach the ground

Using second equation of motion

Where, s = height

u = velocity

g = acceleration due to gravity

t = time

Put the value in the equation

(II). We need to calculate the velocity with which the body reaches the ground

Using first equation of motion

Hence, A body reaches the ground with the velocity of  at time .
