A 328 kg car moving at 19.1 m/s hits from behind another car moving at 13.0 m/s in the same direction. If the second car has a mass of 790 kg and a new speed of 15.1 m/s what is the velocity of the first car after the collision?

A 50 lb child runs at 2.0 m/s and jumps onto a shopping cart and holds on for dear life. The cart has a mass of 40 kg. Assuming the child rides on the cart after the collision. What is the speed of the child and shopping cart just after the child jumps on is? 3.

A 1500 kg car moving to the right with a speed of 20 m/s collides with a bigger car of mass 2000 kg which is at rest. If the two cars lock together, what is their common velocity after the collision?

A car of mass 1388 kg traveling at 18.67 m/s Collided and sticks to another car with a mass of 1488 kg. what is the resulting velocity of the two cars right after the collision assuming that there is no friction present?

A lineback with a mass of 83kg strikes a 71 kg quarterbacker.  The lineback was moving to the left at 5 m/s while the quarterbacker was moving to the right at 1.7 m/s.  a)If the quarterbacker is thrown to the left at 3m/s after the collision, then what is the linebacks velocity after the collision?  b) Determine the change in momentum of each player.

A 5.8 x 104 kg train car at rest is struck from behind by a second train car, traveling at 2.6 m/s. The collision is completely inelastic so the cars stick together. The mass of the second car is 7.4 x 104 kg.

A 98.0-kg parts cart with rubber bumpers rolling 1.20 m/s to the right crashes into a similar cart of mass 125 kg moving left at 0.750 m/s. After the collision, the lighter cart is traveling 0.986 m/s to the left. What is the velocity of the heavier cart after the collision?

A 1500 kg aircraft going 35 m/s collides with a 2000 kg aircraft that is parked and they stick together after the collision and are going 15 m/s after the collision. If they skid for 123.9 m before stopping, how long (in seconds) did they skid?

A car of mass 2900 kg collides with a truck of mass 4400 kg, and just after the collision the car and truck slide along, stuck together. The car's velocity just before the collision was < 39, 0, 0> m/s, and the truck's velocity just before the collision was < -17, 0, 15> m/s.(a) What is the velocity of the stuck-together car and truck just after the collision?

An object with a mass of 8.00 g is moving to the right at 14.0 cm/s when it is overtaken by an object with a mass of 25.0 g moving in the same direction with a speed of 17.0 cm/s. If the collision is elastic, determine the speed of each object after the collision in centimeters per second. 25.0 g object_______________ cm/s   8.00 g object _______________ cm/s
