Question

A bullet leaves a gun with a horizontal velocity of 100 m/s. Calculate the distance it would travel in 1.3 seconds.

a 1247 m
b 0.013 m
c 130 m
d 76.92 m

Answer 1

Ignoring air resistance, the bullet's horizontal velocity is constant:

`v_x=v_(0x)=100\,(\mathrm m)/(\mathrm s)`

In 1.3 seconds, we can expect it to travel

`v_xt=\left(100\,(\mathrm m)/(\mathrm s)\right)(1.3\,\mathrm s)=130\,\mathrm m`
