if a rocket is launched upward from ground level,its height in meters after t seconds is given by h=-9.8t^2+107.8t. during what interval of time will the rocket be higher than 294m? At what timedoes the rocket touch the ground?
Solution
if a rocket is launched upward from ground level,its height in meters after t seconds is given by h=-9.8t^2+107.8t. during what interval of time will the rocket be higher than 294m?
THAT IS ... h=-9.8t^2+107.8t.> 294m.........
-9.8t^2+107.8t- 294 > 0..........
-9.8[T-5][T-6] > 0.........................
[T-5][T-6] < 0
HENCE T SHALL E IN THE INTERVAL ( 5 , 6 ) ............................ANSWER
At what timedoes the rocket touch the ground?
THAT IS .... h=-9.8t^2+107.8t = 0 ....... -9.8[T][T-11] = 0
T=0 .....THAT IS AT START ...................AND ................
T=11 .....................ANSWER
