Problem 1:
Given:
m = 0.30 kg
g = 9.8 m/s²
h = 3 m
Required:
PE
Equation:
PE = mgh
Solution:
PE = mgh
PE = (0.30 kg)(9.8 m/s²)(3 m)
Answer:
8.82 J
---------------------------------------------------------
Problem 2:
Given:
PE = 3,600 J
g = 9.8 m/s²
h = 5.3 m
Required:
m
Equation:
Solution:
Answer:
69.31 kg
---------------------------------------------------------

Answer:
2.40 m
---------------------------------------------------------
Problem 4:
Given:
F = 300 N
∆x = 0.5 m
Required:
PE
Equation:
PE = F∆x
Solution:
PE = F∆x
PE = (300 N)(0.5 m)
Answer:
150 J
