A crate filled with oranges is being pushed across a floor at constant velocity. The mass of the crate is 50 kg. (a) If the frictional force is equal to 100 N, what is the magnitude of the horizontal pushing force? (b) The crate then reaches another section of the store, whose floor has been recently polished so that friction is reduced by 20% of its value in the previous section. What is the acceleration of the crate as it is being pushed by the same force as in part (a)?

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:
