Water is flowing through a horizontal pipe fixed at a height of 2 m above the ground as shown in Fig. 5.90. water strikes ground at a distance of 3m from the pipe. The speed of water as it leaves the pipe is:

Options

A. 47m/s
B. 4.7m/s
C. 9.4m/s
D. 4.9m/s

Answer

b

Explanation

`x=uT=usqrt((2h)/(g))`
`x=usqrt((2h)/(g))`
`3=usqrt((2xx2)/(9.8))`
`u=(3)/(2)sqrt(9.8)=4.7m//s`
