5. The coefficient of static friction between the flat bed of the truck and the crate it carries as shown in Figure 5 is u, = 0.30. (a) Set up the appropriate global axes system and draw the free body, kinematic and kinetic diagrams of the crate on the bed. (b) Determine the maximum acceleration a and hence the maximum velocity Vmx which the truck can acquire from rest in a distance of 50m up a 10-percent grade if the crate is not to slip backward. (c) If the truck was travelling on a horizontal road with the maximum speed you have determined in part (a) above, would the minimum stopping distance be different than 50 m as given above if the crate is not to slip? Give a brief engineering explanation in support of your answer.

As indicated in the illustration, two blocks are connected by an inextensible cable. Block A weighs 178.6 kg, while B weighs 252 kg. If the system is released from rest, calculate the acceleration (in m/s2) of block B. For simplicity, let us suppose that the coefficient of friction between block A and the plane is μk = 0.24 and that the pulley is both weightless and frictionless. Make use of the formula g = 9.81 m/s2.
The conveyor belt shown below is inclined at an angle of 25 degrees. A 3kg package B is placed on the conveyor belt at the position shown with an initial velocity of 0 m/s with respect to the ground. The belt is moving quite fast, and as one could imagine the package is initially slipping, but it's accelerating at a rate of 3.05 m/s^2 until it catches up to the velocity of the belt. If this is the case, find the coefficient of friction between the belt and the package.
