A 1500 kg car traveling at 20 m/s suddenly runs out of gas while approaching the valley shown in the figure(Figure 1). The alert driver immediately puts the car in neutral so that it will roll.​

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

i believe the answer is electric potential.
