The position-time graph describes the motion of a moving object. Describe the motion represented by each segment of the graph.

Find the momentum for a 2.6-kg brick parachuting straight downward at a constant speed of 8.4 m/s .

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!
