Product description
When an open parachute moves, it is affected by the force of air resistance. It is equal to F = k pSv2, where p is the air density, S is the surface area of the parachute, v is the speed and k is a dimensionless coefficient equal to approximately 0.5. What surface must a parachute have in order for a parachutist weighing 80 kg to descend at a speed of 5 m/sec? Compare the resulting area with the area of the room.
