Just before entering the tunnel, you notice the sign that says you must "use the tunnel with your bicycle on foot" but it is too late and you are descending through the tunnel with an initial speed of 6.6 km / h. The tunnel has a semicircular ramp with radius R = 6.3 m, and its mass combined with the mass of the bicycle is 60.3 kg. a) Find the velocity at the bottom of the curve, point 2, for when the friction force is negligible.

For the normal force in the drawing to have the same magnitude at all points on the vertical track, the stunt driver must adjust the speed to be different at different points. Suppose, for example, that the track has a radius of 2.23 m and that the driver goes past point 1 at the bottom with a speed of 24.0 m/s. What speed must she have at point 3, so that the normal force at the top has the same magnitude as it did at the bottom?
