An object is dropped from a height h above the ground. this free-falling object requires 1.02 s to travel the last 39 m before hitting the ground. from what height h above the ground did the object fall?

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.
