Physics

1. Initial Potential Energy (at the top of the incline):

The object starts from rest, so its initial kinetic energy is 0. The potential energy at the top of the incline is given by:

where:

(mass of the object),

(acceleration due to gravity),

is the height of the object at the top of the incline.

 

The height can be found using trigonometry, since the incline is at a 30° angle, and the length of the incline is 10 m. The height is given by:

where:

(length of the incline),
