Figure 9-26 shows graphs of force magnitude versus time for a body involved in a collision. What is the speed of each sphere after the collision, A bullet of mass 30 g is moving at a speed of 200 m/s and it collides head-on with another (stationary) mass (10 g). (a) What is the mass of the other sphere? 1. a). The composite system moves with a speed equal to one fifth the original speed of the 4.16 kg sphe, A sphere of mass M1 = 2.10 kg tied to a string of negligible mass is released from rest, then it hit a sphere of mass M2 = 7.42 kg, which is initially at rest. 3 m/s towards sphere b and collides directly with it a ) What the!
