There is friction between the incline and mass m: the co-efficient of static friction is and the co-efficient of kinetic friction is 3√3. (a) Draw a free-body diagram for each box. √3 m |M| (b) Suppose the box on the incline is not moving, what is the maximum mass the hanging box M could be? What would this be in the case of no friction?

A crate with a mass of 155 kg, starting from rest, slides down a ramp making an angle of 32 degrees with respect to horizontal. The ramp is 3 meters long. A constant frictional force of 100 N acts throughout the motion and a force F is being applied by a rope as shown to prevent the block from sliding too fast.
A mass M = 12.0 kg is pulled up an incline plane by a F = 170 N. The plane angle is 30o with respect to the horizontal. The kinetic coefficient of friction between the surfaces is μ = 0.40. Calculate the acceleration of the block
A 12 kg block sits on a ramp inclined at 11 degrees that has a coefficient of friction of 0.9. A string runs from the block over a pulley at the top of the ramp and then hangs straight down to a suspended weight. If the block slides up the ramp at an acceleration of 1.4 m/s2, find the mass of the suspended weight.
Two blocks are connected by a massless rope over a massless, frictionless pulley, as shown in the figure. The mass of block 2 is m2 12.1 kg, and the coefficient of kinetic friction 0.200.

Formulate a mathematical inequality for the condition that no sliding occurs. There may be more than one inequality.
Problem 2: Peter pushed a 84 kg box down a sloping metal surface with a push force of 50 N. The slope angle o= 16°. The kinetic friction coefficient between the box and the sloping metal surface was u=0.34.
A boy takes 11.8 seconds to slide down a smooth inclined plane of angle such that tan(0) = 1.6, starting from rest. How long (in seconds) he takes to slide down an identical rough inclined plane of friction coefficient 0.71, if he starts from rest?
Many birds can attain very high speeds when diving. Using radar, scientists measured the altitude of a barn swallow in a vertical dive; it dropped 208 m in 3.0 s. The mass of the swallow was estimated to be 0.018 kg, and its cross-section area as 5.6 x 10-4 m2. What was the drag coefficient for this swallow as it dove?
