Person A pulls on a rope that suspends person B, as shown in the figure. If person B and the platform he stands on have a combined mass of 41 kg and the tension in the rope is 263 N, what is the acceleration of person B? Is it up or down? Be sure to draw a FBD of person B + platform.

A stack of two crates is being accelerated upwards by two cables. The cables are directly attached to crate 1 and the tension in each cable is 3248 N. You may assume that the masses of the cables are negligible compared to the masses of the crates. The acceleration of the crates is? bottom crate crate 1 is 109 kg. the top crate is 248 kg.

An Atwood machine consists of two masses hanging from the ends of a rope that passes over a pulley. Assume that the rope and pulley are massless and that there is no friction in the pulley. If the masses have the values ?1=19.5 kg and ?2=12.5 kg, find the magnitude of their acceleration ? and the tension ? in the rope. Use ?=9.81 m/s2.

Two blocks connected by a rope of negligible mass are being dragged by a force at a 21° angle above horizontal (see figure below). Suppose F = 117.0 N, m, = 10.0 kg, m, = 26.0 kg, and the coefficient of kinetic friction between each block and the surface is 0.136. Use g=9.8 m/s?. T m2 (b) Determine the acceleration of the system. m/s2 (c) Determine the tension T in the rope. N

An elevator of mass 300 kg is caused to accelerate upward at 2.5 m/s2 by a force in the cable that supports it. What is the force exerted by the cable (in N) ?

Martha is pushing a 35 kg chair across the floor. The coefficients of friction between the chair and floor are ? s = 0.70 and ? k = 0.40. a. How hard does she need to push horizontally to just start the chair moving? b. If she applies this same force once it is moving, then what is the resulting acceleration? Draw the free-body diagram for this situation.

There are two blocks, masses m₁ and m2, attached by a taut, massless string on a frictionless table as shown in the figure. Mass m₁ is pulled with an acceleration a₁. O M=m₁ + m₂ m2 O M=m₁ O M = m₂ m1 Assume that both blocks have the same acceleration, a₁ = a₂ = a, and if the force required to move the blocks with acceleration a is given by Fnet Ma, what is the appropriate formula for M for our system of two blocks? a1
