To solve the problem step by step, we will use the second equation of motion and the known parameters of the scenario. ### Step 1: Identify the known parameters - Height (s) = -76 m (since the stone is falling downwards) - Time (t) = 6 s - Acceleration (a) = -g = -10 m/s² (taking downward direction as negative) ### Step 2: Write down the second equation of motion ...
