Question

A bullet of mass 0.035 kg is fired horizontally with a speed of 71.7 m/s from a tall bridge. The bullet is in the air for 2.05 s. How far from the base of the bridge does it land?

Answer 1

Given that the bullet is fired horizontally with a speed of 71.7 m/s from the bridge.

So initial horizontal velocity,

Time of flight,

=========================

Consider the horizontal motion of the bullet

There is no acceleration in horizontal direction, so horizontal velocity remains constant.

Horizontal velocity = Horizontal distance/time of flight
