A ball is projected from a point on the floor wilth a speed of 15 m/s at an angle of `60^0` with the horizontal. Will ilt hit a vertical wall 5 m away from the point of projection and perpendiculaer to the plane of projection without and perpendicular to the plane of projection without hitting the floor? will the answer differ if the wall is 22 m away?

Explanation

Here u= 15 m/s, ` theta = 60^0, g= 9.8 m/s^2`
Horizontal range,
`x= (u^2 sin 2theta)/g`
= ((15)2 sin (2x`60^@`)/g`
` 19.88m`
IN the first case the wall is 5 m away from projection point, so it is in the horizontal range of projectile. So the ball will hit he wall. ltbrlt IN the second case (22 m away) wall is notk within the horizontal range. So the ball would not hit the wall.
