Chapter 6, Problem 6.2QQ

A bead slides at constant speed along a curved wire lying on a horizontal surface as shown in Figure 6.8. (a) Draw the vectors representing the force exerted by the wire on the bead at points Ⓐ, Ⓑ,and Ⓒ. (b) Suppose the bead in Figure 6.8 speeds up with constant tangential acceleration as it moves toward the right. Draw the vectors representing the forces on the bead at points Ⓐ, Ⓑ,and Ⓒ.
