A science student holds a 55g egg out a window. Just before the student release the egg the egg has 8.0 j of gravitational potential energy with respect to the ground. How high is the students arm above the ground in meters
The gravitational potential energy is calculated by the product of mass of the object, gravitational acceleration and the height or the elevation of the object. We calculate as follows:
PE = mgh 8.0 J = .055 kg (9.81 m/s^2) (h) h = 14.83 m
