The velocity of a diver just before hitting the water is -8.7 m/s, where the minus sign indicates that her motion is directly downward. What is her displacement during the last 0.98 s of the dive?

  • Physics -

    With an acceleration of gravity of 9.8 m/s^2, the velocity 0.98s earlier was
    -8.7 + 9.6 = +0.9 m/s. (It must have been a springboard drive).

    The average velocity was -3.9 m/s.

    The vertical displacement during the previous 0.98 s was
    -3.9 x 0.98 = -3.8 m
