Problem: A 20-g bullet is fired into a 4-kg block and becomes embeded in it. knowing that the bullet and block then move up the incline for 1.2 seconds before coming to a stop Determine; (a) the Magnitude Of the bullets initial velocity, (b) the Magnitude of the Impulsive force by the bullet on the block. Vb_1=? mk=4kg t=1.2s mb=.02kg I want to use the Princ. Impulse n' Momentum. I have tried: sum(mv_1)=sum(mv_2) but this does not help much I have also thought of using some sort of constant Accel. Eq. Again to no avail. Send me in the right direction.
