In the design of a supermarket, there are to be several rampsconnecting different parts of the store. Customers will haveto push grocery carts up the ramps and it is desirable thatthis not be too difficult. The engineer has done a survey andfound that almost no one complains if the force requiredis no more than 18 N. Ignoring friction, at what maximumangle  θ should the ramps be built, assuming a full 25-kg cart?

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:
