A toboggan and rider, having a total mass of 150 kg, enter horizontally tangent to a 90° circular curve with a velocity V_{A} and the angle _{} of "descent," measured from the horizontal in a vertical x — z plane, at which the toboggan exits at B. Neglect friction in the calculation. The radius r_{B} equals 57 m.

[A].

v_{B} = 21.9 m/s, _{} = 20.9°

[B].

v_{B} = 23.4 m/s, _{} = 29.0°

[C].

v_{B} = 20.7 m/s, _{} = 8.84°

[D].

v_{B} = 20.3 m/s, _{} = 7.37°
