0.50-kg ball traveling at 6.0 m/s collides head-on with a 1.00-kg ball moving in the opposite direction at a velocity of -12.0 m/s. The 0.50-kg ball moves away at -14 m/s after the collision. Find the velocity of the second ball.

Two football players collide head-on in midair while chasing a pass. The first player has a 100.5 kg mass and an initial velocity of 4.20 m/s, while the second player has a 122 kg mass and initial velocity of -3.9 m/s. What is their velocity (in m/s) just after impact if they cling together? (Indicate the direction with the sign of your answer.) m/s

A 75.0-kg paint cart with rubber bumpers is rolling 0.965 m/s to the right and strikes a second cart of mass 85.0 kg moving 1.30 m/s to the left. after the collision, the heavier cart is traveling 0.823 m/s to the right. What is the velocity of the lighter cart after the collision?

A 9.97 kg red car traveling 7.71 m/s to the right collides with a 17.33 kg blue car traveling 7.19 m/s to the left.  What is the velocity of the two cars after the inelastic collision?  Round your answer to 2 decimal places.

A 727.43-kg car traveling east at 24.29 m/s collides with a 549.01-kg car traveling north at 12.42 m/s. What is the final speed of the cars if they stick together.

A 1.825-kg falcon catches a 0.570-kg dove from behind in midair. What is their velocity after impact if the falcon’s velocity is initially 28.5m/s and the dove’s velocity is 8.0m/s in the same direction?

A train of mass m1 = 1400 kg is moving at a velocity of 14 m/s collides with a second train of mass m2 = 2100 kg at rest, after the collision they stick together, what is the final velocity of the train?

A 1.65 kg falcon catches a 0.495 kg dove from behind in midair. What is their velocity after impact if the falcon's velocity is initially 29.5 m/s and the dove's velocity is 5.55 m/s in the same direction?

A 0.20-kg model railroad car moving with a speed of 0.20 m/s is struck from behind by an 0.42-kg model locomotive moving along the same line with a speed of 0.50 m/s. If they stick together after thecollision, what is their velocity?

A light ball of mass 14.7g is at rest on table when a heavier ball of mass 26.3g and moving with an initial velocity of 2.01 m/s collides with but dosent stick to the first ball. After the collision, the lighter ball moves forward with a speed of 2.3 m/s. How fast will the heavier ball move after the collision. Give your answer in meter per second.
