The coefficient μ of kinetic frictions depends on the surfaces in contact and their conditions, while the coefficient μ of static frictions does not depend on the surfaces conditions. a) Trueb) False

There is a worker that slides a heavy box up a ramp into a truck. The box has a mass of 70 kg.  The ramp is 4.7 m long and makes an angle of 27 degrees with the horizontal. The coefficient of friction between the ramp and box is 0.4  1.What's the weight of the box? 2.What's the normal force acting on box? 3.What's the force of friction acting on box?

A stockroom worker pushes a box with mass 11.6 kg on a horizontal surface with a constant speed of 3.40 m/s. The coefficient of kinetic Part A friction between the box and the surface is 0.21. What horizontal force must the worker apply to maintain the motion? Express your answer with the appropriate units. HA ? F = Value Units Submit Request Answer

A mass is on a slope with a coefficient of friction = 0.79. Slowly the angle of the slope is increased. What is the angle in degrees when the mass just starts to slide down the slope?

A sled is on a horizontal surface and a rope with tension T is pulling on it at an angle e above the horizontal. The sled had mass M and does not move due to the frictional force. In this case the coefficient of friction is ug. In terms of the variables given and g, what is the magnitude of the frictional force in this case? Select one: O a. Tcose O b. H, Mgsin0 Ос. Tsin® O d. H, Mgcose
