13-89. The boy of mass 40 kg is sliding down the spiral slideat a constant speed such that his position, measured from thetop of the chute, has components r = 1.5 m, 0 = (0.71) rad,and z = (-0.51) m, where t is in seconds. Determine thecomponents of force F, F, and F, which the slide exerts onhim at the instant i = 2 s. Neglect the size of the boy.r = 1.5 m
