A rocket is launched from rest. After 8.0 min, it is 160 Km above the Earth’s surface and is moving at a speed of 7.6 Km/s. Assuming the rocket moves up in a straight line, what are its (a) average velocity and (b) average acceleration?

  • Physics - ,

    Average velocity = (vertical distance travelled)/ (480 seconds)

    Average acceleration = (velocity change)/(480 seconds)

    They have given you all the numbers you need to compute both.
