Knowledge Thinking (25%) (35%) /10 15 Provided a complete solution for full marks, which may include equations, diagrams, and explanation or assumptions. If a part of a problem depends on a previous answer you have not obtained, assume it and proceed. A. Knowledge [10] 1) A construction worker is using a rope to pull a crate with a mass of 100 kg up a frictionless ramp which makes an angle of 25' with the horizontal It is being pulled with a constant velocity. a) Draw a free body diagram. Label the forces, their components if applicable and angles. [1] b) Calculate the force of tension in the rope. [3] c) Calculate the normal force on the crate. [3]
