A flatbed truck on a horizontal road is loaded with a block whose mass M = 900 kg. Initially the block is at a distance x = 1 m from the back end of the truck bed. The kinetic and static friction coefficients between the block and the flatbed of the truck are µk = 0.30 and µs = 0.32, respectively. The block is not tied down; it is held in place by the frictional force. The truck accelerates uniformly from rest to vf = 108 km/h in t = 12 seconds. What is the work done on the block by the friction force between the block and the flatbed of the truck?

A block is sliding down a ramp at an angle of 0 = 29° to the horizontal. Its initial speed is 1.2 m/s. After sliding 11.9 m along the ramp, it comes to a rest. What is the coefficient of kinetic friction, uk, between the block and the ramp? Ꮎ
A block of mass m1 = 3.9 kg is placed on top of a block with mass m2 = 5.4 kg. A force, F = is applied to m2, at an angle 16.1 degrees above the horizontal. If the coefficient of static friction between all moving surfaces is 0.42 and the coefficient of kinetic friction is 0.32, determine the magnitude of the minimum force that will get the blocks moving.
A delivery company has unloaded a 35 kgkg crate in your driveway. The coefficient of static friction between the crate and the driveway surface is μsμs = 0.30. The coefficient of kinetic friction is μkμk = 0.20. In order to move the crate, you apply a horizontal force of magnitude FF by pushing on it. As a result, the crate slides with an acceleration of 5.0 m/s2m/s2. What is the force F? Express your answer with the appropriate units.

A transport plane takes off from a level landing field with two gliders in tow, one behind the other. The mass of each glider is 700 kg, and the total resistance (air drag plus friction with the runway) on each may be assumed constant and equal to 4300 N. The tension in the towrope between the transport plane and the first glider is not to exceed 12000 N. If a speed of 40 m/s is required for takeoff, what minimum length of runway is needed?
A block is placed on the midpoint of a ramp that is inclined at an angle of 39.8º from the horizontal, at which point the block immediately starts to slide down the ramp due to the fact that the static friction limit for this particular case is insufficient to hold the block in place. If the coefficient of kinetic friction between the block and the ramp is 0.277 , what is the magnitude of the acceleration of the block as it slides down the ramp.
*64. GO A block is pressed against a vertical wall by a force P, as the drawing shows. This force can either push the block upward at a constant ve- locity or allow it to slide downward at a constant velocity. The magnitude of the force is different in the two cases, while the directional angle 0 is the same. Kinetic friction exists between the block and the wall, and the coefficient of kinetic friction is 0.250. The weight of the block is 39.0 N, and the directional angle for the force P is 0 = 30.0°. Determine the magnitude of P when the block slides (a) up the wall and (b) down the wall.
