3. A downhill skier, whose mass is 50.0 kg, attains a speed of 21.0m/s just as she reaches the point where a jump is necessary (point A in the drawing). When she leaves the ground, her velocity is horizontal. In other words she is at the bottom of a vertical circle (radius = 27.0m). Calculate the apparent weight of the skier at this point. %3D 270
