Arubber bullet of mass m=0.025\,\mathrm{kg}m=0.025kg traveling at velocity v_0 = 50\,\mathrm{m/s}v 0 =50m/s hits an iron block of mass m=15\,\mathrm{kg}m=15kg initially hanging at rest from a massless rope. after the collision, the bullet bounced straight back at a velocity of v_1 = 35\,\mathrm{m/s}v 1 =35m/s. the effect of gravity on the bullet alone can be ignored. to what maximum height hh will the iron block reach after the collision? (assume that the rope remains tight during the entire process).
