Transcribed Image Text:The figure shows three blocks at rest. Block A, with a mass of 4.5 kg, is on a horizontal
tabletop and is connected to block B (which has a mass of 3.2 kg) by a rope that passes
around a massless, frictionless pulley. When block C is lifted off block A, block A
accelerates to the right and block B accelerates downward. As block A slides to the right,
a kinetic frictional force with a magnitude of 20 N acts on block A.

- Block A rests on a frictionless table. It is attached to Block B through a massless string over a frictionless pulley. If the mass of Block A is 9 kg and the mass of Block B is 12 kg. What is the magnitude of the acceleration of block B in m/s2?arrow_forwardA toy freight train consists of an engine and three identical cars. The train is moving to the right at constant speed along a straight, level track. Three spring scales are used to connect the cars as follows: spring scale A is located between the engine and the first car; scale B is between the first and second cars; scale C is between the second and third cars. Ignore the weights of the scales. If air resistance and friction are negligible, the relative readings on the three sping scales A, B, and C are the same. What are the relative readings of scales A.

He decides to move them at the same time by pushing on box A with a horizontal pushing force F. = 9.3 N. Here box A has a mass m = 12.1 kg and box B has a mass 7.0 kg. The contact force between the two boxes is F_and N denotes the normal force. (a) What is the acceleration (in m/s) of the two boxes? m/s² (b) What is the force (in N) exerted on m by m?

Narrow_forwardTwo blocks are positioned on surfaces, each inclined at the same angle of 59.6 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 3.24 kg, and this time there is NO friction. What is must be the mass of the white block if both blocks are to slide to the LEFT at an acceleration of 1.5 m/s^2? 6.96 kg 3.09 kg 4.64 kg 1.74 kgarrow_forwardHow far does the car travel before stopping?arrow_forward
- A student takes the elevator up to the fourth floor to see her favorite physics instructor. She stands on the floor of the elevator, which is horizontal. Both the student and the elevator are solid objects, and they both accelerate upward at 5.35 m/s2. This acceleration only occurs briefly at the beginning of the ride up. Her mass is 88.0 kg.
