Question

PART 1. De ne impulse and write an equation for it. 
PART 2. What is the di erence between an elastic collision and an inelastic collision? 
PART 3. State the law of conservation of kinetic energy. 
PART 4. A cart with mass 600 g moving on a frictionless linear air track at an initial speed of 1.5 m/s un-
dergoes an elastic collision with an initially stationary cart of unknown mass. After the collision, the rst cart
continues in its original direction at 1 m/s.
(a) What is the mass of the second cart? 
(b) What is its speed after impact? 
(c) What is the speed of the two-cart center of mass?
