4. Work-Power-Energy 7. A body of mass m, accelerates uniformly from rest to v, in time t,, The instantaneous power delivered to the body as a function of time t is 1. Consider the following two statements. (2003) (2004) A) Linear momentum of a system of particles mv't mvft 4) mv t is zero. 1) 2) 3) B) Kinetic energy of system of particles is A bullet fired into a fixed target loses half of its velocity after penetrating 3 em. How much further it will penetrate before coming to rest assuming that it faces constant resistance to motion ? zero. 8. 1) A does not imply B and B does not imply A. 2) A implies B but B does not imply A 3) A does not imply B but B implies A' 4) A implies B and B implies A, (2005) 1) 3.0 cm 2) 2.0 cm 3) 1.5 cm 4) 1.0 cm 2.
