Question

A bullet comes out of the barrel of length 3m with speed of 800m/s. The average acceleration of bullet is

Answer 1

Initial velocity (u) = 0m/s

Final velocity (v) = 800m/s

Time taken=distance / speed

= 3/800= 0.0037s

So by using the formula

v=u+at we get

800=0+a(0.0037)

=216216.21622m/s^2

= 800/0.0037=
