Two blocks are joined by an inextensible cable as shown. The mass of block A is 192.4 kg and the mass of block B is 260.3 kg. If the system is released from rest, determine the acceleration (in m/s2 ) of block B. Assume that the coefficient of friction between block A and the plane is μk = 0.22 and that the pulley is weightless and frictionless. Round off only on the final answer expressed in 3 decimal places. Use g = 9.81 m/s2
The 65-kg crate is stationary when the force P is applied. Determine the resulting acceleration of the crate if (a) P = 0, (b) P = 223 N, and (c) P = 488 N. The acceleration is positive if up the slope, negative if down the slope. P Part 1 P 65 kg. Incorrect Part (o). We need to decide if the block moves. The easy way to make this decision is to assume that the block does not move and then to test this assumption.
