Answer:

See below ~

Step-by-step explanation:

#1)

  • Gravitational Potential Energy = mgh
  • 100 x 9.8 x 10
  • 9800 J
  • 9.8 kJ

#2)

  • mgh
  • 100 x 9.8 x 0
  • 0 J

#3)

  • mgh
  • 100 x 9.8 x 5
  • 49 x 100
  • 4900 J
  • 4.9 kJ

Answer:
1. 9800J
2. 0J
3. 4900J
Step-by-step explanation:
Gravitational potential energy (GPE) formula is given by:
GPE= mgh
Where: m: is the mass of the person = 100 kg
g: is the gravity of earth = 9.8 N/kg approximately
h: is the height between the position of the person and the ground.
1. h= 10m
GPE= mgh =(100)(9.8)(10)= 9800J
2. h=0m
GPE= mgh =(100)(9.8)(0)= 0J
3. h=5m
GPE= mgh =(100)(9.8)(5)= 4900J
