Question 1 (2 points) A sack of potatoes is held up at rest by three ropes. Two of the ropes are attached to the horizontal ceiling at different angles (see figure). The third is attached to the sack. If the mass of the sack is 30.0 kg, determine the Tension (N) in Rope 2 (T2). Question 2 (2 points) A box of unknown mass is moving down on a frictionless inclined plane. The acceleration of the box is measured as 3.80 m/sz. Determine the angle 9 (degrees) the incline makes with the horizontal. Mass is unknown 3.80 m/s2 \\. 9 (f) 35.0 42.7 Question 3 (2 points) A simple Atwood machine is shown below. If a student is pulling down on the rope on one side of the pully with a force of 40N, determine the tension (N) in the rope. Question 4 (2 points) A block of mass 12.0 kg is lying on the top of a smooth lab bench and is attached by a string over a frictionless light pulley to a vertically hanging mass M2. If the acceleration of the block is 0.800 m/s2, determine M2 (kg). 0 = 0.8 m/s' . 12". f\" smoot h 3.60 (if) 1.07 Question 5 (2 points) A physics student is pushing a small refrigerator up a ramp. The ramp makes an angle of 250 with the horizontal. She pushes on the fridge with a 40.0 N force parallel to the ramp plane. (see figure) The refrigerator has a mass of 15.0 kg and is on wheels so no significant friction is present. Determine the magnitude of the refrigerator's acceleration (m/sz). 0.33 1.47 2.98 4.15
