A object of mass .849kg slids along a frictonless surface. Initally, the object moves with 11m/2 in a direction 15 below the positive x axis. A second object of mass .279kg is now shot from below at v in the positive y direction. It hits the first object and sticks to it. After the impact, the collision it moves in direction 63 above the positive x axis.

1) determine the speed the of 2nd object before impact

2) Determine the final speed collided objects after they stick together
