The height
#H# of a projectile above the ground after#t# seconds is given by the formula#H_t = 1/2*g*t^2 + V_0*t + H_0# ,
where#g# is a physical constant (gravitational acceleration#~~9.8 m/s^2# ),#V_o# is the initial velocity and#H_0# is the initial height.We notice that this is a quadratic equation of variable
#t# .
