Sorin hits a cricket ball straight up into the air. after 1.5\,\text{s}1.5s1, point, 5, start text, s, end text, the ball is falling straight down with a speed of 6.5\,\dfrac{\text{m}}{\text{s}}6.5 s m 6, point, 5, start fraction, start text, m, end text, divided by, start text, s, end text, end fraction. we want to find the initial vertical velocity of the ball. we can ignore air resistance.
