Answer:
<em>The direction of ball will be Number 4 (as can be seen in attached picture) ---- the path of ball will be making some angle when it leaves the tube. </em>
Explanation:
The question is incomplete. So the picture, which is missing in question, is attached for your review.
As it can be seen in the picture, the ball coming out of the tube will have two components of velocity. One is along the length of tube (because ball is moving in that direction and is coming out from the hole), other is velocity component will be perpendicular to the tube (because the ball is made to move in that direction as the tube is rolling on the surface).
<em>So, taking the resultant of two vectors of velocity, the resultant direction of ball will be Number 4 (as can be seen in attached picture) ---- the path of ball will be making some angle when it leaves the tube. </em>

Answer:
411.953 kpa
Explanation:
We have the following assumptions
1. Steady incompressible flow.
2. Burst section water pressure = water main pressure
3. Air and water have negligible friction between them.
Max height = 42 m
Max water density = 277.14k
Density of water
Pwater = 999.8395kg/m
Water gets to 42m because of pressure in the line
P (line) = Pwater * g * h
= 999.8395 x 9.81 x 42
= 411.953Kpa
