4. 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

Show your work for finding the values of each type of energy the object has

Respuesta :

Hi, thank you for posting your question here at Brainly.

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

Answer:

The child has kinetic energy (KE) because she's moving, and gravitational potential energy (GPE) because she's off the ground.

KE = 1/2mv²

KE = 1/2 (20 kg)(5 m/s)²

KE = 50 J

Ug (gravitational potential energy) = mgy

Ug = (20)(9.8)(2) = 392 J

Make sense? Need anything else?
