- Homework Statement
- bullet initial speed 600m/s, mass 15g, penetrates 10cm, average force exerted by post on bullet

- Homework Equations
- f= delta p/t, d=vi+vf/2 *t

used a) change in momentum / time, time from from kinematics equation d = vi+vf/2 *t ... 0.1 = 300*t

=3.33*10^-4

then 600/0.00333 = 1.8*10 ^5

how to proceed?

=3.33*10^-4

then 600/0.00333 = 1.8*10 ^5

how to proceed?
