Engineering Mechanics The time of flight (t) of a projectile on an upward inclined plane is(where u = Velocity of projection, α = Angle of projection, and β = Inclination of the plane with the horizontal.) t = 2u sin (α + β)/g cos β t = g cos β/2u sin (α + β) t = g cos β/2u sin (α - β) t = 2u sin (α - β)/g cos β t = 2u sin (α + β)/g cos β t = g cos β/2u sin (α + β) t = g cos β/2u sin (α - β) t = 2u sin (α - β)/g cos β ANSWER DOWNLOAD EXAMIANS APP
