Acopper refinery produces a copper ingot weighing 150 lb. if the copper is drawn into wire whose diameter is 8.25mm, how many feet of copper can be obtained from the ingot? the density of copper is 8.94 g/cm^3. (assume that the wire is a cylinder whose volume is v=3.14r^2h, where r is its radius and h is its height or length.

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.
