Physics

To calculate the average power delivered by the gravitational force, we need to first find the work done by gravity and then determine the average power.

 

Calculate the work done by gravity

The work done by gravity can be calculated as the force due to gravity acting along the direction of the incline times the distance traveled along the incline. The component of the gravitational force acting along the incline is given by:

Where:

is the mass of the sled (12 kg),

is the acceleration due to gravity (10 m/s²),

is the angle of the incline (37°),

.

 

Substituting the known values:
