Question

A soft ball is on a table 2.4m above the ground. What is the mass of the soft ball if it has a potential energy of 568J.​

Answer 1

Answer:24.15 kg

Explanation:By the formula P.E=mgh,where P.E is potential energy, m is mass of object, g is acceleration due to gravity, and h is the height of object above ground.

From this we get -

568=m(9.8)(2.4)

Therefore, m=24.149 kg or 25.15 kg (approx)
