A 5-kg ball moving at 6 m/sec collides with a 1-kg ball at rest. The balls bounce off each other and the second ball moves in the same direction as the first ball at 10 m/sec. What is the velocity of the first ball after the collision?

An 80 kg running back moving at 5.0 m/s attempts to dive directly across the goal line for a touchdown. Just as he reaches the line, he is met head-on in mid-air by two 75 kg linebackers both moving in the direction opposite the running back at 2.8 m/s. They all become entangled as one mass. What is the velocity of the football players often the collision?

object a, slding on a frictionless surface at 3.2 m/s hits a 2.0 kg object, which is motionless. The collision of A and B is completely ellastic. After the collision, A and B move away from each other at equal and opposite speeds. What is the mass of object A?

Two balls moving in opposite directions have velocities v1ix = 13_m/s and v2i,x = -8_m/s. If their masses are m = 2.5 kg and m2 = 10.kg, respectively, and if their collision is perfectly elastic, then predict the velocity of each ball following the collision.
