Problem 1:

Given:

m = 30 kg

g = 9.8 m/s²

h = 80 m

What is being asked:

PE

Formula to be used:

PE = mgh

Expected unit:

J

Solution:

PE = mgh

PE = (30 kg)(9.8 m/s²)(80 m)

[tex]\boxed{PE = \text{23,520 J}}[/tex]

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

Problem 2:

Given:

m = 10 kg

g = 9.8 m/s²

h = 2 m

What is being asked:

PE

Formula to be used:

PE = mgh

Expected unit:

J

Solution:

PE = mgh

PE = (10 kg)(9.8 m/s²)(2 m)

[tex]\boxed{PE = \text{196 J}}[/tex]

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

Problem 3:

Given:

m = 0.75 kg

g = 9.8 m/s²

h = 0.35 m

What is being asked:

PE

Formula to be used:

PE = mgh

Expected unit:

J

Solution:

PE = mgh

PE = (0.75 kg)(9.8 m/s²)(0.35 m)

[tex]\boxed{PE = \text{2.5725 J}}[/tex]

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

Problem 4:

Given:

m = 1 kg

g = 9.8 m/s²

h = 3 m

What is being asked:

PE

Formula to be used:

PE = mgh

Expected unit:

J

Solution:

PE = mgh

PE = (1 kg)(9.8 m/s²)(3 m)

[tex]\boxed{PE = \text{29.4 J}}[/tex]
