- Needs Complete typed solution with 100 % accuracy.A system comprised blocks, 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 acceleration. A В C.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 = ?
- The block in the figure below has a mass of 5.9 kg and it rests on an incline of angle 0. m 07 You pull on the rope with a force F = 38 N. Assume the incline is smooth and determine the angle of the incline if th moves with constant speed.The pulley and all surfaces are frictionless. Suppose both blocks are made of solid gold. In addition, each block has a mass of 2.38 kg. Find the tension (in N) in the connecting the two gold blocks. Round your answer to 2 decimal places.As in Fig. if the mass of its body is 10 kg. Calculate theacceleration of the body if the coefficient of kinetic friction µk =0.2.
