A rocket carrying a satellite is accelerating straight up from the earth's surface. At 1.25 s after liftoff, the rocket clears the top of its launch platform, 69 m above the ground. After an additional 4.80 s , it is 1.00 km above the ground.
Calculate the magnitude of the average velocity of the rocket for the 4.80 s part of its flight.
Express your answer using two significant figures.
(m/s)
part B:
Calculate the magnitude of the average velocity of the rocket the first 6.05 s of its flight.
