CP3.1 Recall
and use the
equation for
gravitational
A football with a mass of 0.4kg is kicked at a
speed of 20m/s. How much kinetic energy is
stored in the moving ball?

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 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 energy added you so much!
