RS, a light frictionless pulley, and connecting ropes is shown in the figure. The B block has a mass of 9.3 kg and is on a perfectly smooth horizontal table. The surfaces of the A block, which has a mass of 8.2 kg, are rough, with uk = 0.25 between the block and the table. If the C block with mass 9.9 kg accelerates downward when it is released, find its aceleration.

a stalled truck weighing 30kN rests in a level roadway. It is found that a horizontally applied force of 1000N will keep the truck rolling at a constant but low speed of 5.4kph. Extra help is made available and the horizontal push is increased to 1500N. Assume that the truck is moving at 5.4kph. How far did the truck move during the 10 seconds?

Hi I needed help with this. An athlete with a mass of 53.5 kg is doing pushups as shown in the figure below. The value for rW⊥ is 1.00 m and the value for rR⊥ is 1.60 m. (a) Assuming she moves upward at a constant speed, determine the force she must exert on the floor with each hand to do a push-up.(b) The triceps muscle in the back of her upper arm with an effective lever arm of rT⊥ = 1.70 cm, as shown in the figure below, and she exerts force on the floor a horizontal distance of r 'R⊥ = 2.05 cm from the elbow joint. Determine the force in the triceps muscle.In order to appreciate the strength of the triceps, determine the ratio of the force in the tricep muscle to her weight (in decimal form). FT/W = ?

A cord passing over a pulley connects two masses, as shown, where m, = 3.60 kg and m, = 7.10 kg. The system accelerates with a magnitude of 1.34 m/s?. The coefficient of kinetic friction between the masses and the incline is the same for both masses. Assume the pulley is frictionless, and the cord is massless. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) m2 m, 35.0° 35.0° (a) What is the coefficient of kinetic friction?

A m1 = 1.65-kg aluminum block and a m2 = 6.05-kg copper block are connected by a light string over a frictionless pulley. The two blocks are allowed to move on a fixed steel block wedge (of angle ? = 34.0°) as shown in the figure. (For aluminum on steel, ?s = 0.61 and ?k = 0.47. For copper on steel, ?s = 0.53 and ?k = 0.36.)
