What are the three factors needed for Newton’s Second Law?

Newton's second law of motion is also known as law of acceleration.

Force, mass and acceleration are the three factors needed two explain the law.

Explanation:

This law states that if there is an unbalanced force acted upon an object (either in rest or in motion ) the force causes an acceleration. The acceleration is directly proportional to the force.

F(net)α a, the proportionality constant is the mass of the object.

Another definition for the law is

F(net)= m.a      where m stands for mass and a is acceleration.

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

+15-35=-20
