The discussion focuses on calculating the time it takes for a stone, falling from a building at an initial speed of 32 m/s and with a weight of 24 N, to reach the ground. Given that air resistance is negligible, the calculation utilizes the formula for uniformly accelerated motion. The time can be determined using the equation: time = (final velocity - initial velocity) / acceleration due to gravity, where the acceleration is approximately 9.81 m/s². The final velocity upon impact can be calculated, leading to a definitive time of approximately 3.26 seconds for the stone to reach the ground.

Air resistance is so small that it can be neglected.
the weight of the stone is 24N.
Calculate the time in second which the stone takes to reache the ground.
