Question

a golfer drives a ball toward a lake.The golf ball was struck at an angle of 27 above the horizontal with a speed of 5.6m/s.How far did the ball travel horizontally before hitting the water

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 $u = 5.6m/s$, $\theta = 27\degree$ and $g = 9.8m/s^2$

$$R = \dfrac{5.6^2\cdot \sin(2\cdot 27\degree)}{9.8} \approx 2.6m$$

Answer. 2.6 m.
