Suppose that while moving into an apartment you move a refrigerator into place by sliding it across the floor. The refrigerator weighs 1600 N and the coefficient of static friction between the floor and the refrigerator is 0.44. What is the least force you could exert on the refrigerator to move it?
A sled weighing 237 N rests on a 15° incline, held in place bystatic friction. The coefficient of static friction is 0.50.(a) What is the magnitude of the normal force on the sled?(b) What is the magnitude of the static friction on the sled?(c) The sled is now pulled up the incline at constant speed by achild. The child weighs 543 N and pulls on the rope with a constantforce of 100 N. The rope makes an angle of 30° with the incline andhas negligible weight. What is the magnitude of the kineticfriction force on the sled? (Enter 0 if sled does not move.)(d) What is the coefficient of kinetic friction between the sledand the incline? (Enter 0 if sled does not move.)(e) What is the magnitude of the force exerted on the child by theincline?
(a) What is the minimum force of friction required to hold the system of the figure below in equilibrium?
(b) What coefficient of static friction between the 100-N block and the table ensures equilibrium?
(c) If the coefficient of kinetic friction between the 100-N block and the table is 0.250, what hanging weight should replace the 50-N weight to allow the system to move at a constant speed once it is set in motion?
