A model rocket is launched with an initial upward velocity of 50 m/s. The rocket height h (in meters) after t seconds is given by the following H=50t-5t2
Find the value of t

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
