Answer:
Time= 2,24 seconds
Explanation:
In the vertical movement you have an accelerated movement where the acceleration is gravity.
You have to use the equation
[tex]v=vo-gt\\\\v= final velocity (0 m/s)\\\\vo= Initial velocity (11 m/s)\\\\g= gravity (9.8 m/s^{2} )[/tex]
t= 1,122 ( this will be the rise time)
To know the total time you must multiply 2, because you have to ssume that the shot returns back to its original height
total time= 2*1,122= 2,244 seconds
