On a horizontal table, puck A has an initial speed of 1.4 m/s heading south of east, making an angle of 35 with the horizontal, while puck B is heading north. After the collision, puck B is heading north of east with a speed of 0.5m/s, making an angle of 48 with the horizontal. Puck A was found to be heading east after the collision. Determine the initial speed of puck B, in m/s. The two pucks are identical and have the same mass.
