Adisa pulls a 40-n crate up a 5.0-m long inclined plane at a constant velocity. if the plane is inclined at an angle of 37° to the horizontal and there is a constant force of friction of 10 n between the crate and the surface, what is the net change in potential energy of the crate?

To solve this problem we resort to the concept of potential energy which is given by the equation

Where,

m= mass

g= Gravitational acceleration

h = Height

The height is given in the form of a component, that is, it is given the length that is 5 m and the angle of 37 degrees, therefore the height would be

Applying the potential energy formula we have to

Therefore the net change in potential energy of the crate is 120J.

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
