What is the magnitude of the acceleration of the system

Reference no: EM13807851

Q1:

A block of mass 3.92 kg lies on a frictionless horizontal surface. The block is connected by a cord passing over a pulley to another block
of mass 3.97 kg which hangs in the air, as shown. Assume the cord to be light (massless and weightless) and unstretchable and the pulley to have no friction and no rotational inertia.

The suspended 3 kg mass on the left is moving up, the 4 kg mass slides to the right on the table, and the suspended mass 6 kg on the right is moving down.

The acceleration of gravity is 9.8 m/s².

What is the magnitude of the acceleration of the system?

Q6: A 9.5 kg bucket of water is raised from a well by a rope.

The acceleration of gravity is 9.8 m/s².

If the upward acceleration of the bucket is 3.7 m/s², find the force exerted by the rope on the bucket. Use g = 9.8 m/s².

a) What is the tension T in the left-hand cable slanted at an angle of θ with respect to the wall?

Q7: Consider the 604 N weight held by two cables shown below. The left-hand cable had tension T and makes an angle of θ with the wall. The right-hand cable had tension 730 N and makes an angle of 27^o with the ceiling.

a) What is the tension T in the left-hand cable slanted at an angle of θ with respect to the wall?
