Question

What is the difference in PE
between a 2.00 kg mass 3.00 m
high, and a 4.00 kg mass 5.00 m
high?
(Unit = J)​

Answer 1

Answer: 137.34J

Explanation:

Use ewuation for potential energy:

Pe=mgh

m1=2kg

m2=4kg

h1=3m

h2=5 m

----------------------------

Pe1=m1gh1

Pe1=2kg*3m*9.81m/s²=58.86 J

Pe2=m2*g*h2

Pe2=4kg*9.81 m/s²*5m

Pe2=196.2 J
