A projectile is fired from the origin O with initial velocity (5i + 29j) ms'. The projectile just clears a of height 20 m which is at a horizontal distance x from O. The plane of the wall is perpendicular to the vector i. Find the possible values of x. Find, also, the corresponding values of the velocity of the projectile when it is just passing over the wall. (Take g as 10 ms-2.)

Answer detailly 5

A projectile is fired from the origin O with initial velocity (5i + 29j) ms'. The projectile just clears a wall of height 20 m which is at a horizontal distance x from O. The plane of the wall is perpendicular to the vector i. Find the possible values of r. Find, also, the corresponding values of the velocity of the projectile when it is just passing over the wall. 5. (Take g as 10 ms-2.)
