Question

A stream of water gushes from an open pipe at an angle of 15o from the horizontal. If water comes out of the pipe at a speed of 15 m/s, how far from the pipe will the water land?

Answer 1

The range is given as follows (https://courses.lumenlearning.com/boundless-physics/chapter/projectile-motion/):

$$R = \dfrac{u^2\sin (2\theta)}{g}$$

where $u = 15m/s$, $\theta = 15\degree$ and $g = 9.8m/s^2$

$$R = \dfrac{15^2\cdot \sin(2\cdot 15\degree)}{9.8} \approx 11m$$

Answer. 11 m.
