To calculate the potential energy of the child with respect to the ground, we can use the formula for gravitational potential energy: Potential Energy (PE) = mgh Where: - m = mass of the child = 75.0 kg- g = acceleration due to gravity = 9.81 m/s^2 (standard value on Earth)- h = height = 6.00 cm = 0.06 m (converted to meters) Substitute the given values into the formula: PE = 75.0 kg * 9.81 m/s^2 * 0.06 mPE = 44.145 J
