Question

Calculate the Potential Energy of the cart at the top of the initial hill. The mass of the cart is 900 kg, the height of the initial hill is 60 m, and the acceleration of gravity is g = 9.8 m/s².

Answer 1

The potential energy of the cart with a mass of 900 kg at the top of a 60 m hill is 529.2 kilojoules, calculated using the formula PE = mgh.

Step-by-step explanation:

To calculate the potential energy (PE) of the cart at the top of the initial hill, we use the formula PE = mgh, where m is the mass of the cart, g is the acceleration due to gravity, and h is the height of the hill. Plugging in the values provided: m = 900 kg, g = 9.8 m/s², and h = 60 m, the calculation is as follows:

PE = 900 kg × 9.8 m/s² × 60 m

PE = 529200 J, or 529.2 kJ

Thus, the potential energy of the cart at the top of the hill is 529.2 kilojoules.
