Pls help if you get it right ill give blc my science thing is not on here but it science. i'm given a good amount so pls try thank you

Drag each label to the correct location on the image.

Jessica is visiting a park with her mother. Jessica sits on a swing. Her mother pulls the swing to a height of 3 meters above the ground and lets it go. The image shows Jessica at three positions on the swing. Jessica‘s mass is 44 kilograms and the maximum velocity of the swing is 5 meters/second. What’s the energy she has at each position shown? Ignore friction and air resistance. Use g = 9.8 m/s2, PE = m × g × h, and KE =1 /2 mv2

KE = 0 joules

KE = 550 joules

PE = 862.4 joules

Pls help if you get it right ill give blc my science thing is not on here but it science-example-1

Answer:

Position at maximum height

PE = mgh

PE = 44kg *9.8m/s²*3

PE = 1,294 J

Position at minimum height

PE = 0 J

Position at maximum velocity

KE = 1/2*mv²

KE = 1/2*44kg*(5m/s²)²

KE = 550 J

Position at minimum velocity

KE = 0 J
