Pаrticle A оf mаss 2.00 kg mоves tо the eаst with a speed 10.0 m/s and particle B of mass 1.50 kg moves to the north. They suffer a collision. After the collision, particle A moves 60.0° north of east with a speed 10.0 m/s and particle B moves 15.0° south of east. (a) What are the speeds of particle B before and after the collision? (b) What are the magnitude and direction of the impulse that particle A exerts on particle B? (c) What is the change of kinetic energy of the two-particle system before and after the collision? If particle A  moving to the east with a speed 10.0 m/s and particle B moving to the north with the speed determined in (a) stick together after the collision, (d) what are the magnitude and direction of the velocity of the particles after the collision and (e) what are the magnitude and direction of the impulse that particle B exerts on particle A?
