Question

In the figure a fastidious worker pushes directly along the handle of a mop with a force F. The handle is at an angle 0-42° with the
vertical, and u, -0.68 and p₁,-0.49 are the coefficients of static and kinetic friction between the head of the mop and the floor. Ignore
the mass of the handle and assume that all the mop's mass m-0.73 kg is in its head. (a) If the mop head moves along the floor with a
constant velocity, then what is F? (b) If @ is less than a certain value 00. then F (still directed along the handle) is unable to move the
mop head. Find 0.

Calculate the maximum deceleration of a car that is heading down a 6º slope (one that makes an angle of 6º with the horizontal) under the following road conditions. You may assume that the weight of the car is evenly distributed on all four tires and that the coefficient of static friction is involved—that is, the tires are not allowed to slip during the deceleration. (Ignore rolling.) Calculate for a car: (a) On dry concrete. (b) On wet concrete. (c) On ice, assuming that µs = 0.100 , the same as for shoes on ice.
