Two bumper cars each have a mass of 112 kg. Connie's car is moving at 3.12 m/s, and Bonnie's car is at rest when Connie runs into her. After the collision, Bonnie's car lurches forward at a speed of 1.32 m/s. Connie has a mass of 70 kg, and Bonnie has a mass of 82 kg. What is the post collision speed of Connie's car?

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?
