Answer:
Potential energy = 13.23 J
Step-by-step explanation:
Given that,
The mass of the loaded cart, m = 3 kg
Its height of the seat top is 0.45 m
We need to find the potential energy of the loaded cart on top of the ramp. We know that, the potential energy of an object is due to its height. It can be given by the formula as follows :
![E=mgh\\\\E=3\ kg* 9.8\ m/s^2* 0.45\ m\\\\E=13.23\ J](https://img.qammunity.org/2021/formulas/physics/high-school/b31k2x39fphu92iy5x29g7wbvca3e3xh8h.png)
So, the required potential energy is 13.23 J.
