A car rolls down a ramp in a parking garage. The horizontal position of the car in meters over time is shown below. Graph of horizontal position x (in meters) on y axis and time (in seconds) on x axis. The initial position is -3 m at t=0 s, and the position increases linearly to 3 m at t=8 s. Then the position is constant at 3 m until t=16 s, then increases linearly to 9 m at t=24 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!
