- Why is energy conserved in an elastic collision but not in an inelastic collision?Let's assume a perfectly elastic collision between a golf club (mass of 250 gr) and a golf ball (mass of 46 gr). If the club hits the ball at a speed of 45 m/sec what will be the speed of the ball after the impact? What happens if the mass of the club is doubled?A cart with mass 330 g moving on a frictionless linear air track at an initial speed of 1.8 m/s undergoes an elastic collision with an initially stationary cart of unknown mass. After the collision, the first cart continues in its original direction at 1.1 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?

- A man who could only find a 75-kg blue rock nearby decides to drive a metal beach umbrella pole down into the soft sand of Galveston beach by dropping it straight down from a resting height of 2.3 meters. If the blue rock does not rebound off the pole just after contact (that means bouncing back and possibly hitting him in the head) then calculate the impulse the rock places on the umbrella pole. Assume the metal beach umbrella has a total mass of 175-kgA tennis ball of mass 57.0 g is held just above a basketball of mass 607 g. With their centers v as shown in the figure below. | (a) Find the magnitude of the downward velocity with which the basketbal reaches the ground. m/s (b) Assume that an elastic collision with the ground instantaneously reverses the velocity of the basketball while the tennis ball is stis moving down.
