A skier leaves a ramp and flies 2 meters into the air before falling 5 meters and landing lower on the mountain. Compare the KE and PE as he leaves the ramp, at his highest point in the air, and when he lands on the ground.

Question

A javelin thrower finds they can throw a 800g javelin 50m, a 600g javelin 58m and a 250 g spear the same size only 30m. Explain why the same amount of throwing energy produces these 3 results.

If the diver is moving at 1.4 m/s when she is 2.2 m above the pool what is her KE and PE? (round answer to 1 decimal place and use proper units.)

As a diver jumps from the board potential and kinetic energy are
transformed into one another. Describe the 2 types of energy as
the diver moves from the board to the water.

Answer 1

So we're both here, huh?

Answer 2

@anon yes T_T
