2 - A student launches a toy model rocket from the top of a building. The

rocket lands on a target on the ground below (shattering to pieces after the

parachute fails to open). The equation for the rocket's height in meters is

given by A(t)=-\dfrac{4}{10}(t-30)^2+650A(t)=-104(t-30)2+650 where it is

the time in seconds after launch. Use the equation (not a graph) to answer

the following questions. https://www.youtube.com/watch?
