Question

object initially at rest explodes into three picces. Piece A has a mass of 5 kg, B has a mass of 3.0 kg, and C has a mass of 2.5 kg. After the explosion, As velocity is (3.0 m/s)i + (2.0 m/s) j and Bs velocity is (2.0 m/s)i - (3.0 m/s) j y at rest explodes into three pieces. Piece A has a mass of 5.0 a. What is Cs velocity after the explosion? b. Calculate the change in kinetic energy during the explosion. c. Is this collision elastic or inelastic? Explain. d. Is internal energy lost, gained, or unchanged? Explain.
