a load of 5kg is attached to the free end of a wire length 2m and diameter 0.6mm of the extension of the wire is 0.2 calculate the young modulus of the material of the wire (g=9.8m/s²)​

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.
