The lower block of mass m2 = 3.2 kg is pulled on by a rope with a tension force of 28 N. The upper block has mass m1 = 1.8 kg. The coefficient of kinetic friction between the lower block and the surface is 0.32. The coefficient of kinetic friction between the lower block and the upper block is also 0.32. What is the acceleration of the 3.2 kg block?
The 54-lb block rests on the rough surface for which the coefficient of kinetic friction is μk = 0.2. A force F=(40+s2)lb, where s is in ft, acts on the block in the direction shown. The spring is originally unstretched (s= 0) and the block is at rest. (Figure 1) Figure 1 of 1A picture shows a block laying on a horizontal surface with a spring of stiffness k equal to 20 pounds per foot attached to its right side. The other end of the spring is pressed against the wall. Force F is pushing the block to the right and downwards, at an angle of 30 degrees below the horizontal. Determine the power developed by the force the instant the block has moved s = 1.5 ft.
Two bodies A and B, each weighing 96.6 lb, are connected by a rigid bar of negligible weight attached to them at their gravity centers. The coefficient of friction at the wall and floor is 0.268 if the bodies start from rest at the given position, determine the acceleration of B at this instant. Simplify the solution by creating dynamic equilibrium and taking a moment summation about the intersection of the wall and floor reactions. Explain why these reactions pass through the gravity center of B and A respectively.
URGENT Collar A slides over the smooth vertical bar shown in the figure. The masses Wa = 10lbs and WB = 5lbs. When h = 0.12192m, the spring is unextended. When the system is in equilibrium, h = 0m. Determine the constant k of the spring. Note: The normal of the collar is 100 times its mass (that of the collar), remember that g = 32.16 ft/s2.
The boxes in the picture (A has a mass of 1.6kg and B has a mass of 4.4kg) are connected with an unstretchable and massless rope. They are released from rest at a level with an angle θ = 50∘.

The roller-coaster car depicted in Figure Q3 has an empty mass of 700 kg. Additionally, the passenger inside has a mass of 75 kg. The car is released from rest at the top of the hill at A. Friction, mass of the wheels and the size of the car can be neglected. (a) Determine the minimum height of the hill crest (h) so that the car travels around inside of the loop without leaving the track. (b) Determine the maximum constant braking force which may be applied at B so that the car stops on the ground immediately after exiting the loop.
