From the top of a cliff, a person throws two stones. The cliff is 20.9 m high. The two stones have idential intial speed of 19.8 m/s and are both thrown at an angle of 36.3, one stone was thrown below the horizontal and one above the horizontal. What is the distance between the points where the stones strike the water? Neglect air resistance.

Expert Solution

Step 1

Calculate the horizontal and vertical component of the initial velocity.

$\begin{array}{l} u_{H} = (19.8 m/s) \cos 36.3 ° = 15.957 m/s \\ u_{V} = (19.8 m/s) \sin 36.3 ° = 11.72 m/s \end{array}$
