Example 7The boy of mas 40kg is sliding down the spiral slide at a constant speed such that his position, measured from the top of the chute, has components
Determine the components of force which the slide exerts on him at the instant t=2s. Neglect the boys size.

Example 8
The 0.5 lb particle is guided along the circular path using the slotted arm guide. If the arm has an angular velocity of 4 rad/s and an angular acceleration of 8 rad/s2 ath the instant θ=30°, determine the force of the guide on the particle. Motion occurs in the horizontal plane.
