Question

Puck A of mass 240-g is traveling due east with a speed, , on a level, frictionless air table when it collides with puck B of mass 160 g traveling at 40° south of west with a speed, , on the same table. (See the diagram below.) When the pucks collide, they stick together via Velcro surfaces that line the circular boundaries of both pucks. Find the magnitude and direction of the momentum of the tandem of pucks after the collision. Draw the final momentum vector into the diagram below at the point of the collision.

Puck A of mass 240-g is traveling due east with a speed, Vai = 10, on a level, frictionless air table when it collides with puck B of mass 160 g traveling at 40° south of west with a speed, VBI = 15, on the same table. (See the diagram below.) When the pucks collide, they stick together via Velcro surfaces that line the circular boundaries of both pucks. Find the magnitude and direction of the momentum of the tandem of pucks after the collision. Draw the final momentum vector into the diagram below at the point of the collision.
