A 60.0 kilogram man holding two 0.90o kilogram bricks stand on a 2.60 kilogram skateboard. Initially, the skateboard and the man are at rest. The man now throws the two bricks at the equivalent time therefore that their speed relative to the man is 17.0 m/s. Find the recoil speed of the man and the skateboard relative to the ground, assuming the skateboard moves without friction?
