Explanation:
When an object is thrown at an angle θ with the horizontal . It covers the parabolic path . We can calculate the time of flight by the relation
T = [tex]\frac{2usin\theta}{g}[/tex]
here u is the initial velocity and g is acceleration due to gravity .
and T is time of flight .
Thus if we increase the initial velocity , the time of flight also increases and vice versa .
