Find the time for the combined filters to reach the ground

Reference no: EM13288762

Coffee filters behave like small parachutes, with a drag force that is proportional to the velocity squared, Fdrag = Kv2. A single coffee filter, when dropped from a height of 2.2 m, reaches the ground in a time of 4.6 s. When a second coffee filter is nestled within the first, the drag force remains the same, but the weight is doubled. Find the time for the combined filters to reach the ground. (Neglect the brief period when the filters are accelerating up to their terminal speed.)
