Question

exercise ball is on a table 2 m above the ground. What is the mass of the ball if it has a GPE of 40

Answer 1

Answer:

mass of the ball is 8.16

Explanation:

Given - g = 9.8

h = 2

gpe = 40

we know that

gpe = mgh

40= m×9.8×2

40/19.6 = m

therefore m = 8.16

note- if you took g = 10 the mass will be 8
