Two blocks are connected by a rope that passes over a set of pulleys. one block has a weight of 412 n, and the other has a weight of 908 n. the rope and the pulleys are massless and there is no friction.
(a) what is the acceleration of the lighter block?
(b) suppose that the heavier block is removed, and a downward force of 908 n is provided by someone pulling on the rope, as part b of the drawing shows. find the acceleration of the remaining block.
(c) explain why the answers in (a) and (b) are different.

Part a determine the magnitude of the x component of f using scalar notation. fx f x = nothing lb request answer part b determine the magnitude of the y component of f using scalar notation. fy f y = nothing lb request answer part c determine the magnitude of the z component of f using scalar notation. fz f z = nothing lb request answer provide feedback figure1 of 1a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component. a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component.
