A collar with a mass of m can slide along a smooth (frictionless) shaft with angle α measured from horizontal direction. The collar is attached to a light spring with stiffness k and unstarched length a. The other end of spring is attached to a fixed point). The collar starts from rest in A when it is pulled by a force P which is constant. P is at an angle β measured from the shaft. β is constant as well. Find the speed vB of the collar in the time instant it is at point B. (Given Parameters: m, a, b , k, P, α, and β)

Aball thrown by ginger is moving upward through the air. diagram a shows a box with a downward arrow. diagram b shows a box with an upward arrow. diagram c shows a box with a downward and upward arrow equal in size. diagram d shows a box with a downward and upward arrow with the downward arrow larger in size. which force diagram represents the forces on the ball? you may neglect the effects of air resistance.
