Question

A body projected at an angle with the horizontal has a range 300 m. If the time of flight is 6 s, then the horizontal component of velocity is

Answer 1

Horizontal range = 300 m

Time of flight = 6 s

Since, there is no acceleration in the horizontal direction. The horizontal component of the velocity will stay constant.

Let the horizontal component of the velocity be v.

Now,

$v = \frac{Range}{Time}$

$v = \frac{300}{6}$

v = 50 m/s

Hence, the horizontal component of the velocity is 50 m/s.
