Sled during the impact-how much energy was lost in impact

Reference no: EM13551704

A child's sled has rails that slide with little friction across the snow. Logan has an old wooden sled with heavy iron rails that has a mass of 8.0kg quite a bit for a 28kg child! Logan runs at 4.0m/s and leaps onto the stationary sled and holds on tight as it slides forward. The impact time with the sled is 0.20s . Part A Immediately after Logan jumps on the sled, how fast is it moving? What was the force on the sled during the impact? How much energy was "lost" in the impact?
