Two balls with masses 3 kg and 2 kg move toward each other, collide head-on, and stick together after the collision (a perfectly inelastic collision). Before the collision the 3-kg ball moves with a speed of 5 m/s and the 2-kg ball moves with a speed of 10 m/s. Neglect friction. See the figure above. What is the velocity of the balls after the collision? a. -2 m/s b. -1 m/s c. 3 m/s d. 5 m/s

A 5 kg blob of clay is moving forward at 2 m/s when it has an inelastic collision with a 2kg blob of clay initially at rest. What will be the final velocity of the two blobs after they stick together?

Before collision, there are two objects.1st object M1 = 8 kg V1 = 3m/s2nd object M2 = 4 kg V2 = 0 m/s After collision, these two object stick together and move together.What is the speed after the collision?

A 2 kg blob of puty moving at 3 m/s slams into a 2 kg blob of putty at rest. what is the speed of the two stuck together blob of putty immediately after collision?   A. 0.66 m/s   B. 1.5 m/s   C. 1m/s   D. 0 m/s

A 600-kg car headed north and an 800-kg car headed west collide at anintersection. After the collision, the 600-kg car is skidding at a speed of 22 m/s ata direction of 25º north of west. The 800 kg car is going 34 m/s at a direction of32º west of north.a. What were the initial speeds of the cars?b. What was the change in energy of the system due to the collision?

Two carts on a track are headed toward each other, and have a head-on collision.Cart 1 has a mass of 2 kg and is traveling at 3 m/s, and Cart 2 has a mass of 3 kgand is traveling at 1.5 m/s. After the collision, Cart 2 has a speed of 0.75 m/s inthe opposite direction it was originally traveling.a. What is the speed and direction of cart 1 after the collision?b. What is the change in energy during this collision? Is it elastic?c. What type of collision is it?

1. The dynamics TAs want to do an experiment with bowling balls to figure out their velocity after colliding. Bowling ball A has a mass of 3kg and is moving at 8 m/s to the right and it makes a direct collision with bowling ball B, which has a mass of 2 kg and is moving 4 m/s to the left. If e=0.7, what is the velocity and direction of each bowling ball just after the collision. You can neglect the size of the bowling balls. [Ans. To Check: va=0.16m/s←] 8 m/s 4m/s B

A 1600 kg car traveling at 20.0 m/s collides with a 2200 kg car travelling in the same direction 14.0 m/s. The two cars stick, together after the collision. a. What is the speed of the two cars after the collision? b. How much energy is lost in the collision?
