The tallest volcano in the solar system is the
29 km tall Martian volcano, Olympus Mons.
An astronaut drops a ball off the rim of the
crater and that the free fall acceleration of the
ball remains constant throughout the ball’s
29 km fall at a value of 4.1 m/s2. (We assume
that the crater is as deep as the volcano is tall,
which is not usually the case in nature.)
Find the time for the ball to reach the crater

  • Physics -

    y = yi + vi t + (1/2) a t^2
    yi = 29*10^3
    y = 0 at bottom
    vi = 0
    a = - 4.1
    0 = 29*10^3 - 2.05 t^2
    t = 119 seconds = about two minutes
