# A child jumps from a moving sled with a speed of 2.5 m/s and in the direction opposite the sled’s motion. The sled continues to move in the forward direction, but with a new speed of 6.3 m/s. If the child has a mass of 38 kg and the sled has a mass 63 kg, what is the initial velocity of the sled?
