Jill threw a dodgeball completely horizontal in x-direction with velocity of +5 m/s and mass of .5 kg. At the same time her friend threw a dodgeball with the same mass in the -x direction and a velocity of -2 m/s. The balls hit each other, and Jill's ball was deflected 30° above the original path, while her friend's deflected 20⁰. below the initial path. a. Ignoring gravity, solve the velocity of each ball after the collision, using a free body diagram. b. If both balls had a magnitude of 3 m/s, how much kinetic energy was "lost" during the collision?

Two billiard balls of equal mass undergo a perfectly elastic head-on collision. Part A If one ball's initial speed was 2.40 m/sm/s, and the other's was 3.40 m/sm/s in the opposite direction, what will be their velocities after the collision? Enter your answers numerically separated by a comma. Enter positive value if the direction of the velocity is the same as the direction of the initial velocity of the first ball, and negative value if the direction of the velocity is opposite to the direction of the initial velocity of the first ball.
