a rope attached to the block. The ramp makes an angle of 14° with the horizontal, and the rope is parallel to the ramp. Each worker can pull with a force of maximum magnitude 400N. Z Draw a force diagram of the situation described. (4 marks) V Calculate the tension in the rope, giving your answer to two significant figures. Find the minimum number of workers needed to hold the block. State and justify any two, significant, assumptions you have applied to your calculations in parts (b)and (c). (5 marks)
