1. An 80 kg man is running east at 15 m/s. What is his momentum? 2. An 8 kg box is moving along a frictionless, horizontal floor. At some point, the box experiences a steady 5 N force that is applied parallel to the floor in the direction of movement for 7 seconds. a) What is the magnitude of the change in momentum of the box? b) What is the magnitude of the impulse applied to the box? c) What would we need to know in order to find the final velocity of the box? 1.
