Engineering Mechanics The Cartesian equation of trajectory is (where u = Velocity of projection, α = Angle of projection, and x, y = Co-ordinates of any point on the trajectory after t seconds.) y = (gx²/2u² cos²α) + x. tanα y = x. tanα - (gx²/2u² cos²α) y = (gx²/2u² cos²α) - x. tanα y = x. tanα + (gx²/2u² cos²α) y = (gx²/2u² cos²α) + x. tanα y = x. tanα - (gx²/2u² cos²α) y = (gx²/2u² cos²α) - x. tanα y = x. tanα + (gx²/2u² cos²α) ANSWER DOWNLOAD EXAMIANS APP
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 = 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) ANSWER DOWNLOAD EXAMIANS APP
