Body A in Fig. 6-36 weighs 96 N, and body B weighs 72 N. The coefficients of friction between A and the incline are μs = 0.40 and μk = 0.25. Angle θ is 40°. Let the positive direction of an x axis be down the slope. What is the acceleration of A if A is initially (a) at rest, (b) moving up the...

A 5.10 kg block is sent sliding up a plane inclined at θ = 37.0° while a horizontal force F of magnitude 50.0 N acts on it. The coefficient of kinetic friction between block and plane is 0.310. (a) What is the magnitude of block's acceleration? (b) The block's initial speed is 4.10 m/s. How...

A firefighter with a weight of 744 N slides down a vertical pole with an acceleration of 3.03 m/s2, directed downward. What are the magnitudes and directions (choose the positive direction up) of the vertical forces (a) on the firefighter from the pole and (b) on the pole from the firefighter...

a chain consisting of five links, each of mass 0.102 kg, is lifted vertically with a constant acceleration of magnitude a = 2.03 m/s2. Find the magnitudes of (a) the force on link 1 from link 2, (b) the force on link 2 from link 3, (c) the force on link 3 from link 4, and (d) the force on link 4...
