Equations for average and maximum velocity

  1. May 9, 2015 #1
    1. The problem statement, all variables and given/known data
    Given height dropped and gravity constant, what is the maximum and average velocity of an object dropped from a building.
    Gravity- 9.81
    (Delta)y- 45 m. Height from which object is dropped
    T- 3.1 seconds

    2. Relevant equations
    V= v(final)-v(initial)= a x (delta)t
    V(avg)= (sqrt (2 x g x (delta)y)) / 2

    3. The attempt at a solution
    I'm not looking for the answers, just reassurance I'm on the right track and using the right equations. So above I think I have the right equation for maximum velocity for the first equation and average velocity for the second equation.

    The formulas are right, but the average velocity can be calculated in a much easier way.
