Question 640556: The height of a rocket in meters t seconds after it is launched is approximated by the polynomial 0.5 at2 + vt + h where a is always -9.8, v is the initial velocity, and h is the initial height. Marie and Bob launched their rockets at the same time from a platform 5 meters above the ground. Marie launched the 4400i and Bob launched the Q99. How much higher was Marie's rocket after 2 seconds? The Velocity of Q99 is 90 and the Velocity of 4400i is 125.

\ =\ -4.9t^2\ +\ 125t\ +\ 5)
\ =\ -4.9t^2\ +\ 90t\ +\ 5)
\ =\ h_M(t)\ -\ h_B(t)\ = 35t)
Evaluate )
