A particle is projected from origin in xy-plane and its equation ,of trajectory is given by `y = ax - bx^(2)`. The only acceleration ,in the motion is' f' which is constant and in `-ve` direction of, y-axis.
(a) Find the velocity of projection and the angle of projection.
(b) Point of projection is considered as origin and x-axis along the horizontal ground. Find the horizontal range: and maximum height of projectile. Projectile completes its flight in horizonal plane of projection.
