A 180-lb snowboarder has speed v = 18
ft/sec when in the position shown on the
halfpipe. Determine the normal force on his
snowboard and the magnitude of his total
acceleration at the instant depicted. Use a
value HK = 0.07 for the coefficient of kinetic
friction between the snowboard and the
surface. Neglect the weight of the
snowboard and assume that the mass center
G of the snowboarder is 2.2 feet from the
surface of the snow.

The system is released from rest in the position shown. Calculate the tension T in the cord and the acceleration a (positive
if to the right, negative if to the left) of the 23-kg block. The small pulley attached to the block has negligible mass and
friction. (Suggestion: First establish the kinematic relationship between the accelerations of the two bodies.)
