"WebJan 10, 2024 · 2) Air resistance - this force acts upward, and it is not constant: it is proportional to the velocity of the skydiver. where k is a constant and v is the velocity. Therefore, as the skydiver falls down, its velocity increases and the air resistance increases as well. The equation of forces for the skydiver is therefore: " - How does a skydiver achieve terminal velocity

How does a skydiver achieve terminal velocity

WebA skydiver jumps from a plane and wishes to achieve "terminal velocity." A possible model for the skydiver's velocity is given as.The combined mass of the skydiver and her various gear is 60 kilograms, and the acceleration due to gravity g, near the Earth, is 9.8 meters per second squared. WebWhat does a skydiver achieve terminal velocity? While flying face-down, jumpers indeed have an average terminal velocity of 120 mph, but if they are 'freeflying' - which means adapting your body position to fly in other orientations such as 'head-up' and 'head-down' - the average terminal velocity is more like 160mph.
