Question

a 400 g bead slides on a curved frictionless wire, starting from rest at point a. find the speed of the bead at point b and point c.

Answer 1

In getting the speed of the bead at point b and point c first identify each of the data and first get the speed of point A to B and then to point B and Point C. In my calculation using a derived formula the speed of A to B -s 9.9m/s and the speed of B to C is 7.67m/s
