What speed should a satellite with a mass of 1500 kg at 8,500 km above the center of the Earth be travelling at in order to
stay in orbit (remember, the mass of the Earth is 5.97 x 1024 kg)

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.
