Three blocks, light connecting ropes, and a light frictionless pulley comprise a system, as shown in the figure. An external force of magnitude P is applied downward on block A, causing block A to accelerate downward at a constant 2.5 m/s2. The tension in the rope connecting block B and block C is equal to 60 N.
What is the magnitude of the force P?
What is the mass of block C?
Please include detailed answers with net force equations.
Assume that the three blocks in Figure P4.27 move on a frictionless surface and that a 42.0 N force acts as shown on the number 3 block. The masses of the three blocks are m1 = 0.7 kg, m2 = 3.0 kg and m3 = 4.4 kg. Determine the acceleration given this system. Determine the tension in the cord connecting the number 3 and the number 1 blocks. Determine the force exerted by the number 1 block on the number 2 block.
Consider the system shown in the figure. Block A weighs 40.7 N and block B weighs 31.0 N. Once block B is set into downward motion, it descends at a constant speed.
a. Calculate the coefficient of kinetic friction between block A and the tabletop.
b. A cat, also of weight 40.7 N, falls asleep on top of block A. If block B is now set into downward motion, what is its acceleration magnitude?
