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.
