Question 1 The box in the figure above has a mass of 3.25 kg, and is being pushed against a wall by a force /(F)Ivec), at an angle 8= 42.09. What magnitude of force is necessary to cause the box to slide down the wall at a constant speed? (Assume there is no friction) O 42.9 N O 21.3 N O 23.7 N O 47.6 NQuestion 2 A group of construction workers are building a house and want to lower down an excess bundle of 2240 kg bricks to ground. They tie one end of a rope to the bundle of bricks, loop it through a pulley, and tie the other end of the rope to a toolbox. If the coefficient of kinetic friction between the toolbox and the floor is 0.400 and the acceleration of the bundle of bricks is 6.85 m/s', what is the mass of the toolbox? O 1.81x10= kg O 614 kg O 2.57x10# kg O 2.26*10# kg Question 3 In the figure provided, a 165 kg crate, to the right of the pulley, is released from rest and begins to fall to the ground. If the mass on the left is m = 110. kg, what is the magnitude of the tension of the rope attached to the 165 kg crate? Assume the rope and pulley are massless. O 1.08x102 N O 1.29x10- N O 1.62x10# N O 647 N
