A ball is projected obliquely with velocity 49m/s strike the ground at a distance 245m from the point of projection, for how long was the ball in air?

7.07 secs

Let the angle of projection be A.
Range R = 245 m u = 49 m/s g = 9.8 m/s

R = u^2 sin2A / g
so sin2A = R * g/u^2 = 1 => A =45 deg.

Time of flight = R/(u cosA) = 245 *√2 /49 = 5√2 = 7.07 seconds.

T=√2H÷g ( time of flight formula)
T=√2×245÷9.8m/s
=√490÷9.8=√50
=7.07seconds
