Find an expression for v0v0v_0, the initial speed of the fired object. Express your answer in terms of some or all of the variables mmm, MMM, LLL, and θθtheta and the acceleration due to gravity, ggg.

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.
