A lump of granite with a mass of 11. kilograms is launched into a stationary 70. kilogram block. After they collide, the granite becomes stuck in the block. If the total momentum after the collision is 85.
kilograms * meters per second, what was the speed the granite hit the block with?

Since the investigative question has two variables, you need to focus on each one separately. thinking only about the first part of the question, mass, what might be a hypothesis that would illustrate the relationship between mass and kinetic energy? use the format of "if…then…because…” when writing your hypothesis.

In a heat engine if 1000 j of heat enters the system the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2000 j? 1. write the equation 2.list out your known variables 3.plug the numbers into the equations 4.solve 5.write your solution statement that includes initial energy and final
