A man holding a rock sits on a sled that is sliding across a frozen lake (negligible friction) with a speed of 0.530 m/s. The total mass of the sled, man, and rock is 94.5 kg. The mass of the rock is 0.250 kg and the man can throw it with a speed of 14.5 m/s. Both speeds are relative to the ground. Determine the speed of the sled (in m/s) if the man throws the rock forward (i.e., in the direction the sled is moving).   m/s Determine the speed of the sled (in m/s) if the man throws the rock directly backward.
