Answer:
It will not hit.
Step-by-step explanation:
In this problem, we need to tell that was the cannonball able to hit its target of 50 meters when the initial velocity was 20 m/s.
When it will hit the target, final velocity, v = 0
Using third equation of motion as follows :

Here, a =-g

The target is in a straight line 50m away on the x-axis. As 50m is far from 20.40 m and that’s why it won’t hit.
