a boy of mass 40kg is sliding down the spiral slide at a constant speed such that his position is measured by
theta=(0.7t) rad
and
z=(-0.5t) m
where t is in seconds. How do you find the components of forces Fr, Ftheta and Fz which the slide exerts on teh boy at the instant when t=2s. Neglect the size of the boy.
