An object's resistance to any change in its motion is the
of the object

Inertia.

Explanation: The property of the objects to stay in a state of relative equilibrium or relative motion is called inertia.

Is the resistance that the matter does against changes in his state of motion, where these changes can be changes in velocity or direction of movement. Where bigger inertia means a bigger resistance of the object against changes in its movement.

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
