To find the time of flight for an object thrown at an angle, we can use the formula:
where:-
is the time of flight,-
is the initial velocity,-
is the angle of projection, and-
is the acceleration due to gravity.Given:-
-
-
First, calculate the sine of the angle:
Now, substitute the values into the formula:
Simplify the expression:
Therefore, the object remains in the air for 2.5 seconds.
