Question

HELP PLS Directions: For each situation, you need to determine if the object has KE or GPE or both. Then find their values. Be sure to include the correct units, 3. A 20-kg child is tossed up into the air by her parent. The child is 2 meters off the ground traveling 5 m/s.

Circle one: KE / GPE / both

Answer 1

BOTH.

m=20kg v=5m/s h=2m g=9.8

GPE = mgh = 20*9.8*2 = 392 J

KE = 1/2*mv^2 = 1/2*20*5^2 = 250J
