A rocket carrying a satellite is accelerating straight up from the earth's surface. At 1.20 after liftoff, the rocket clears the top of its launch platform, 68 above the ground. After an additional 4.85 , it is 1.50 above the ground.Calculate the magnitude of the average velocity of the rocket for the 4.85 part of its flight. Calculate the magnitude of the average velocity of the rocket the first 6.05 of its flight.
