*15-112. A toboggan and rider, having a total mass of
150 kg, enter horizontally tangent to a 90° circular curve
with a velocity of va = 70 km/h. If the track is flat and
banked at an angle of 60°, determine the speed vg and the
angle e of “descent," measured from the horizontal in a
vertical x-z plane, at which the toboggan exists at B. Neglect
friction in the calculation.

A ball is attached to one end of a string with a length of 18 cm, while the other end is anchored at a fixed point O. The ball rotates in a horizontal circle as depicted. The string's maximum tension capacity is 3.70 times the ball's weight before it risks breaking. Determine the highest speed in meters per second at which the ball can rotate without causing the string to snap. [Assume there is no air resistance, and the acceleration due to gravity is 9.80 m/s²].
