A man holding a rock sits on a sled that is sliding across afrozen lake (negligible friction) with a speed of 0.490 m/s. Thetotal mass of the sled, man, and rock is 95.0 kg. The mass of therock is 0.260 kg and the man can throw it with a speed of 16.0 m/s.Both speeds are relative to the ground.
Determine the speed of the sled (in m/s) if the man throws therock 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 therock directly backward.
_______m/s
