An object experiences an acceleration of -6.4 m/s^2. As a result, it accelerates from 54 m/s to a complete stop. How much distance did it travel during that acceleration?

A1-lb collar is attached to a spring and slides without friction along a circular rod in a vertical plane. the spring has an undeformed length of 5 in. and a constant k =25 lb/ft. knowing that the collar is released from being held at a determine, the speed of the collar and the normal force between the collar and the rod as the collar passes through b.
