Question

DUE TONIGHT HURRY PLS I give 30 pts

A 20-kg child is tossed up into the air by her parent. The child 2 meters off the ground traveling 5 m/s

KE, GPE, or both

EXPLAIN PLS

Answer 1

The answer is both.

For kinetic energy:

KE = 1/2*m*v^2 = 0.5*20,000 grams*5 = 50,000 J

For gravitational potential energy:

Pe = mgh = 20,000 grams*9.81 m/s^2*2 m = 392.2 J
