INITIALLY @ REST A child pushes a sled across the horizontal ground covered with snow, with a force of 40-Newtons for 5 seconds. The mass of the sled is 20-kilograms. a. What impulse does the child give the sled? b. What is the momentum of the sled after 5 seconds? C. If a stationary child (who has a mass of 30-kilograms) jumps onto the sled, what will be the new speed of the sled?
