Two identical cars are moving along a straight line towards each other at the same speed. If they have a completely inelastic collision: A. That means they bounce off each other B. That means they stick to each other C. Need more info to know what that means
Two identical cars are moving along a straight line towards each other at the same speed. If they have a completely inelastic collision, what is the speed of the wreckage after the crash? • Need more info to know • Zero • Double their original speed
Two identical cars are moving towards – this time they are moving perpendicular to each other but still at the same speed. If they have a completely inelastic collision, what direction will the wreckage slide after the crash? • Need more info to know • At 45o
A car moving North has a completely inelastic collision with a car moving West. If the wreckage moves more North than West we know: • The North car was moving faster • The North car had more mass • The North car had more momentum
Ball A rolls into a stationary Ball B. After the collision, Ball A is going the opposite direction. Which ball has more mass? • Ball A • Ball B • Need more info to know for sure
