1. The problem statement, all variables and given/known data A bullet with a mass of 0.005 kg and moving with a speed of 400 m/s penetrates a distance of 0.08m into a wooden block firmly attached to the Earth. Assume that the force stops it is constant. Compute for: a.) acceleration of the bullet b.) accelerating force c.) time of acceleration d.) impulse of the bullet 2. Relevant equations I think I'll use a=-Vi^2 / 2s. for the acceleration of the bullet. then for the acceleration of the bullet, F=m(Vf-Vi) then for the time of acceleration, t = m(Vf-Vi) / F am i right?
