a toy rocket is launched from a 1.4m high platform in such a way that its heigh, h (in meters), after t seconds is given by the equation h= -4.9t+9.1t+1.4. How long will it take for the rocket to hit the ground
----------
h= -4.9t+9.1t+1.4
When it hits the ground, h = 0
-4.9t+9.1t+1.4 = 0
Solve for t.
