To solve the problem of finding the angle at which a stone must be thrown from a cliff to achieve maximum range, we can follow these steps: ### Step 1: Understand the problem We have a stone thrown from a height of 4.2 m with an initial velocity of 20 m/s. We need to find the angle of projection (θ) that maximizes the horizontal range (R) on the ground below. ### Step 2: Break down the motion The motion can be analyzed in two components: horizontal and vertical. The horizontal component of the velocity is given by: \[ V_x = V \cos(\theta) \] ...
