Kinematics of a Particle

Time of flight: The time interval during which the projectile is in motion is called time of flight.

We will study the case when the projectile flies over an inclined plane. A horizontal surface is a special case of an inclined plane.

Let AB be a plane inclined at an angle b to the horizontal as shown in the figure below. A projectile is fired up the plane from point A with initial velocity u m/sec and an angle a. Now, the range on inclined plane AB and the time of flight are to be determined.
