The 10­-kg block rests on the smooth incline. if the spring is initially stretched 0.5 m, determine the total work on the block when a horizontal force pushes the block up the plane s = 2 m. how does the work done by a spring force change with the spring constant?

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!
