Question

Potential energy calculation - MxGxH. Gravity equals 10. How much

potential energy does a 5 gram golf ball that is falling from 40 ft have? Use
your calculator if need be. *

Answer 1

Ep = 0.6095 [J]

Step-by-step explanation:

As defined in the problem statement, potential energy is defined as the product of mass by gravity by height. But first we must convert all the values given to measures of the international system (SI)

g = gravity = 10 [m/s^2]

h = elevation = 40 [ft] = 12.19 [m]

m = mass = 5 [g] = 0.005 [kg]

Ep = potential energy [J]

Ep = 0.005*10*12.19 = 0.6095 [J]
