Question

what is the potential energy of a 7kg bird that is 60m above the ground?
potential energy (j) mass (kg) height (m)
what is the kinetic energy of the box in j? 4116

Explanation:

Step1: Recall the formula for gravitational potential energy

The formula for gravitational potential energy is \(U = mgh\), where \(m\) is the mass, \(g\) is the acceleration due to gravity (\(g = 9.8\space m/s^{2}\)), and \(h\) is the height.

Step2: Substitute the given values into the formula

Given \(m = 7\space kg\), \(h=60\space m\), and \(g = 9.8\space m/s^{2}\).
