An object of mass 4m, initially at rest, explodes breaking into two fragments of mass m and 3m, respectively. Which one of the following statements concerning the fragments after the explosion is true? O The smaller fragment will have twice the speed of the larger fragment. O The smaller fragment will have three times the speed of the larger fragment. O They will fly off at right angles. O They will fly off in the same direction. O The larger fragment will have three times the speed of the smaller fragment.A stationary homo explodes in space breaking into a number of small fragments. At the location of the explosion, the net force due to gravity is zero newtons. Which one of the following statements concerning this event is true'? C} Kinetic energy.f is consented in this process. C} All of the fragments must have equal kinetic energies. {E} The sum of the kinetic energies of the fragments must be zero. C} The vector sum of the linear momenta of the fragments must be zero. C} The mass of an}.r one fragment must be equal to the mass of an}.' other fragment
