In this question we've been told that a pipe discharges water into a creek.
00:04
The water comes out of the pipe with a horizontal velocity of 1 .5 m.
00:09
2nd per second and the end of the pipe is 3 .1 meter above the creek.
00:13
We need to find out how far out from the end of the pipe is the point where the stream of water meets the creek.
00:22
So we know that the water comes out with the horizontal velocity of 1 .5 and the height of the end of the pipe from the creek is 3 .1.
00:33
So the edge is going to be 3 .1 meter.
00:36
We need to find out the distance from the end of the pipe to where the stream of water meets the creek.
00:46
So suppose the stream of water will move the path is going to be like this.
00:53
So it meets here.
00:55
So we need to find out distance, the horizontal distance covered by the water from the end of the pipe.
01:03
So we need to find out this distance x.
01:09
So this is a very simple question of projectile motion.
01:12
So initially we know that the horizontal velocity is 1 .5 m.
01:18
This is going to the vertical velocity is going to be 0 because there's nothing acting on it.
01:25
We know the vertical distance.
01:28
So the distance is 3 .1 meter.
01:34
We need to find out the horizontal distance...
