    a displacement question

    hey there, i have a problem that states that a ball is shot vertically upward with a speed of 2.15x10^2 m/s. what will be the position of the ball 32.6s after it was fired?

    The answer i got was 1.80x10^2 m.

    does this seem to be correct, i was having trouble finding the most appropriate equation for this problem. Thanks for any help you can offer.

    The equation I believe you want is

    y=v_it-\frac{1}{2}gt^2,

    where v_i= initial velocity, and g=9.80 \,\text{m/s}^2
