A uniform metal tube of length 5m and mass 9kg is suspended horizontally by two vertical wires attached at 50cm and 150cm respectively from the ends of the tube. Find the tension in each wire.

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
