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.(adsbygoogle = window.adsbygoogle || []).push({});

I am having trouble solving this problem. I used this equation:

vf1=(0.165-2.00)/(0.165+2.00)*705, but the answer is wrong. Am I using the right equation?
