A projectile is given a horixontal projedctio from a heigh 9h) with velocity (u) What is the nature of trajectory of the projectile ? Draw the accleration- time graph of this trajectory. What does its slope lindicate ?

Explanation

When a projecdtile is given a horizontal projection from a height, soon after the projection it will be having two mutually perpendicular velocities (i) Horizontal velocity (u) which remains constant throughout the motion and (ii) vertical downward velocity wich increases with time, due gravity pull.
The acceleration of projectile is constant with time acting vertically downwards (=g). Therefore, the graph between acceleration (a) -time (t) of this projectile motion is a straight line ` AB` parallelto time axis. Fig. 1 9d). 35. The slope of this straight line is zero with time axis. It shows that there is is no change in acceleration of projectile with time
