A 1.5 kg ball rises upward 2.0 m above the ground when it is thrown straight up. Use the ground as your reference point ( ) for gravitational potential energy. The kinetic energy of the ball at ground level is closest to: a. 0.0 J b. 3.0 J c. 9.8 J d. 19.6 J e. 29.4 J

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!
