2 balls collide and bounce off of each other. During the collision total momentum remained constant and total kinetic energy remained constant. What type of collision is this?

• Inelastic Collision

• Elastic Collision

• Perfectly Inelastic Collision

• No collision occurred

A 2 250 kg Tesla going 15.0 m/s collides with a parked 3 190 kg Dodge Ram. During the collision they stick together as they deform. The two vehicles then travel at 6.20 m/s.

What is the momentum of the Tesla before the crash?

• 14,000 kg m/s

• 19,800 kg m/s

• 33,800 kg m/s

• 47,900 kg m/s
