They each have a mass of 1.0 x 10kg and a radius of 1.0 x 10 m. They are initially at rest with respect to each other. As measured from that rest frame, how fast are they moving when (a) their separation has decreased to one-half its initial value and (b) they are about to collide?

Answer 1

sos: given, A = 1x10!! (distance bostan) 29 m = mg - 10 ra- 10²m 1 kg there moment are time. ༼ (a) Initially Us - Gummy and since at rest zero. Thus by symmetore they each must be maving auth the same speed in apposite died at any subsequent At half that distance, Uge 9 = 2u = - aby my du - GYR dke -du So for each stay Ka Curso 5x my? 0.5 x mv
