Suppose all of the apples have a mass of 0.10 kg. if apple (a) is sitting on the ground, what is its potential energy?

0.10 j
9.8 j
0.0 j
1.0 j

Answer is option c) 0.0 Joules

Explanation:

Potential energy is the energy possessed by the object with respect to its position to other object.

Formula to calculate potential energy

Potential energy (PE) = m×g×h -------------------------- Equation (1)

m – mass (Kg)

g – Acceleration due to gravity

h – height (m)

Given data:  

Mass = 0.1 Kg.

Apple is sitting on the ground, therefore height of the Apple is 0. put h=0 in Equation 1

PE of Apple A = 0.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
