Included Quiz Questions
Ball A with a velocity of 2 m/s to the right and ball B with a velocity of 3 m/s to the left collide head on. The final velocity of ball A is 2 m/s to the left and ball B is 1 m/s to the right. Balls A and B have the same mass. Is this collision elastic or inelastic?
- Inelastic collision because the total kinetic energy is not conserved but total momentum is conserved
- Elastic collision because the total kinetic energy and total momentum are conserved
- Inelastic collision because the total kinetic energy and total momentum are not conserved
- Elastic collision because the total kinetic energy is not conserved but total momentum is conserved
- Inelastic collision because the total kinetic energy and total momentum are conserved
A 3,000 kg truck travelling at 50 km/hr strikes a stationary car of mass 1,000 kg. The 2 vehicles are locked together after the collision. What is the final speed of the 2 vehicles?
- 37.5 km/hr
- 37 km/hr
- 0 km/hr
- 50 km/hr
- 38 km/hr
Two clay balls are thrown toward each other. One has a mass of 4 kg and a velocity of 6 m/s to the right, and the other has a mass of 2 kg and a velocity of 4 m/s to the left. If they collide completely inelastically (i.e. stick together), what will be the velocity of the resulting 6 kg clay ball after the collision?
- 8/3 m/s to the right
- 8/3 m/s to the left
- 16/3 m/s to the right
- 16/3 m/s to the left
- 0 m/s
