Let's suppose mass changes smoothly from 5 kg to 2 kg in 10 s. During this same interval of time the object goes from 0 m/s to 120 m/s (again let's say smoothly.) 1. Create mass and velocity as a function of time equations Can you use these to give the Mom(t) equation? 2. What is the momentum at time = 3 s? 3. What is the Force as a function of time equation? 4. What is the force at times 0, 3, 7 and 10 s?
