Question

How much GPE does a cannonball of mass ${5}{kg}$ gain ascending to the top floor of the Eiffel tower, ${276}{m}$ above the ground?

Answer 1

Gravitational Potential Energy (GPE) = m x g x h

m = Mass

g = Acceleration due to gravity (Earth's gravitational pull =  9.80665 m/s^2)

h = height

 

∴ GPE = 5kg x 9.80665 m/s^2 x 276m

∴ GPE = 13533.12 J

 

Answer 2

m =5 kg g = 9,80665 m/s^2 h = 276 m GPE =? GPE = mch = 5x9,80665x276 = 13533,177J

GPE = mgh I had a typing error on da formula
