A rocket carrying a satellite is accelerating straight up from the earth's surface. At 1.10 s after liftoff, the rocket clears the top of its launch platform, 50m above the ground. After an additional 4.80 s, it is 1.20km above the ground.
1- Calculate the magnitude of the average velocity of the rocket for the 4.80 s part of its flight
2- Calculate the magnitude of the average velocity of the rocket the first 5.90 of its flight.
