Question

A 15 kg mass is lifted to a height of 2m. What is gravitational potential energy at this position

Answer 1

294.3 J

Step-by-step explanation:

U = mgh

U = energy

m = mass

g = gravity

h = height

so

U = 15kg * 9.81 m/s^2 * 2m

294.3 J (joules) [kg *m^2/s^2]

Answer 2

Answer: 294J

Step-by-step explanation:

`U_g=mg(y_f-y_i)`

`U_g=(15)(9.8)(2-0)=294J`
