Answer: 3675 J
Step-by-step explanation:
Well, hello, buddy! Back again, are we? No matter.
notice how 9.8 is in meters per second squared because it is gravity
the equation for potential energy is
[tex]PE = mgh[/tex]
where m is mass in kilograms and g is gravity in its usual form which i just listed above. and here height is in meters
just multiply everything together... its cake, isnt it? strawberry cake.. easy as pie
75 x 9.8 x 5
3675 J
