4.4 • A man is dragging a trunk up the loading ramp of a mover's truck. The ramp has a slope angle of 20.0°, and the man pulls upward with a force F whose direction makes an angle of 30.0° with the ramp (Fig. E4.4). (a) How large a force F is necessary for the component F, parallel to the ramp to be 90.0 N? (b) How large will the component F, perpendicular to the ramp be then?

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
