Part A nsider the heaviest box of 150 lb that you can push at stant speed across a level floor, where the coefficient of etic friction is 0.45, and estimate the maximum horizontal ce that you can apply to the box. A box sits on a ramp that is lined at an angle of 60.0° above the horizontal. The efficient of kinetic friction between the box and the ramp is If you apply the same magnitude force, now parallel to the ramp, that you applied to the box on the floor, what is the heaviest box (in pounds) that you can push up the ramp at constant speed? (In both cases assume you can give enough extra push to get the box started moving.) Express your answer in pounds. 5. m = lb Submit Request Answer

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:
