A 0.900 kg bead slides on a curved wire, starting from rest at point A in Figure P5.28. If the wire is frictionless, find each of the following. (a) the speed of the bead at B m/s (b) the speed at C m/s

8 m/s^2), and h is the height of point A above some reference level. From the diagram, we can see that h = 0.5 m. Therefore, the potential energy at point A is: PE(A) = (0.900 kg)(9.8 m/s^2)(0.5 m) = 4.41 J Show more…
