A 30g bullet with a horizontal velocity of 500m/s comes to a stop 12 cm within a solid wall.

a) what is the change in its mechanical energy?

b) What is the magnitude of the average force from the wall stopping it?

a) what would I use of the equation? Can you please explain what i would do? I am confused

b)Would I use F= ma?a) The original mechanical energy is the kinetic energy. It goes from

(1/2) M Vo^2 to zero. Vo is the initial velocity, 500 m/s

b) (average Force) x (stopping distance) = mechanical energy loss

Solve for the average force
