a Speeding Bullet The fastest commercially available rifle bullet claims a muzzle velocity of 4225 ft>s. How far (in meters) can this bullet travel in 5.0 ms?

Respuesta :

ANSWER

21.125 m

EXPLANATION

Assuming the bullet has a constant velocity of 4225 ft/s when fired, the distance it travels in t seconds is:

[tex]\begin{gathered} v=\frac{d}{t} \\ d=v\cdot t \end{gathered}[/tex]

If we want to find the distance in 5 ms, we have to multiply it by the velocity but we have to use the same units:

[tex]5ms=0.005s[/tex]

The distance is then:

[tex]d=4225\frac{ft}{s}\cdot0.005s=21.125m[/tex]
