4. Bullets are fired from gun at a rate of 15.0 rounds per second with a spacing of
60.0 m between the individual rounds.
a) What is the speed of the bullets fired by this gun?

15.0
=
=
= 15.0

= 60.0


= = 15.0 60.0 = 9.00 10! /
b) Determine the rate of fire required to have 45.0 m of spacing between the
rounds.

= 45.0
=

9.00 10! /
=
= 20.0

45.0
