Reading Check. Write arguments. How can you be sure that the skater leaping through the air is moving faster than the one speeding along the ground?

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.

hope this : )

explanation:

pe = weightxheight = 2000x1000=2,000,000joules

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

+15-35=-20

going in opposite directions
