Question

Conservation of moment in two dimensions Mech HW-62 2. Two objects collide on a level, frictionless table. The mass of object A is 50 kg: the mass of object B is 3.0 kg. The objects stick together after the collision. The initial velocity of object A and the final velocity of both objects are shown. After collision Before collision BA (One side of a square represents 0.1 m/s) a. In the space provided, draw separate arrows for object A and for object B representing the direction of Direction of AF the change in momentum vector of the object. Object A Object B is the magnitude of the change in momentum of object A greater than, less than or equal to that of object B? Explain your reasoning. Po b. System C is the system of both objects A and B combined. How does the momentum of system C before the collision compare to the momentum of system C after the collision? Discuss both magnitude and direction. (Each side of a square represents 0.4 kgm/s) Construct and label a vector showing the momentum of system C at an instant before the collision. Show your work clearly. c. Construct and label a vector showing the initial velocity of object B. Show your work clearly. (Each side of a square represents 0.1 m/s
