The Quadratic Formula - Defintion & Examples

An elementary school is enjoying a field day. Marissa is competing in the bean bag toss, a game where the students try to throw bean bags as far as they can. $\\$ If Marissa throws the bean bag with an initial velocity $v_{0}$ of $10$ meters per second from an initial height $h_{0}$ of $3$ feet, how many seconds will the bean bag be in the air? $\\$ Use the equation $h(t)=-\frac12gt^2+v_{0}t+h_{0}$ with the force of gravity $g=9.8$ to find the total number of seconds.
