6. The 35-kg child is sliding down the spiral slide at a constant speed such that their position,
measured from the top of the chute, has components r = 1.5 m, 0 = (0.7t) rad, and z =
(-0.4t) m, where t is in seconds. Determine the components of force F, Fa, F, which the slide
exerts on the child at the instant t = 2 s. Neglect the size of the child.
r = 1.5 m
