A 0.165 kg projectile is fired with a velocity of +705 m/s at a 2.00 kg wooden block that rests on a frictionless table. The velocity of the block, immediately after the projectile passes through it, is +55.0 m/s. Find the velocity with which the projectile exits from the block. I used the equation vf1=(m1-m2)/(m1+m2) but I got the wrong answer. Can you please help me?
