A 3 kg ball traveling to the left at a velocity of 2.3 m/s collides with another 0.5 kg
ball traveling to the left at 0.3 m/s. As a result of the collision, the 3 kg ball moves to
the left with a velocity of 1.73 m/s. Using the conservation of momentum, calculate
the velocity of the 0.5 kg ball after the collision. Show all your work. Use the
simulation to verify your answer. --
In a head-on collision, two isolated particles m, = 7 kg and m2 = 5 kg collide with initial speed
Vii = 4 m/s and v2i = 6 m/s as shown in Figure 1. After collision m, rebounds with speed vif
