An 80-kilogram cliff diver is standing on a cliff that is30 meters high. a. What it the potential energy of the cliff diver?

b. The diver makes his dive. What is his potential energywhen he is 10 meters above the water surface?

c. What is the kinetic energy of the diver when he istraveling at 19.6 m/s during his dive?

d. What is the potential energy of the diver when he istraveling at 19.6 m/s?

What is the average speed of a car that travels 40mph for 1 hour and 60 mph in another hour will mark brainliest

How would a small bar magnet be oriented when placed at position x?

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!
