Three balls roll on a frictionless surface and collide in two separate collisions. Ball 1 (mass m1=1.0 kg and velocity v1i-10 m/s) collides first with Ball 2 (mass m2-3 kg and velocity v2i=0 m/s) in an inelastic collision. Ball 2 then collides with Ball 3 (mass m3-0.7 kg and velocity v3i=5 m/s) in a perfectly inelastic collision. If Ball 1 moves with a velocity v1f-2.5 m/s to the left after its collision, what is the final velocity (v3f) of the combined balls (2 and 3) after their collision in m/s? Assume all three balls move only in the x direction. If your answer is negative (moving to the left), include the negative in your entry. Round your answer to 2 decimal places for entry into Canvas. Do not enter units. Example: 1.23 m₁1 m1 m2 m3

A space probe, initially at rest, undergoes an internal mechanical malfunction and breaks into three pieces. One piece of mass ml = 48.0 kg travels in the positive x-direction at 12.0 m/s, and a second piece of mass m2 = 62.0 kg travels in the xy-plane at an angle of 105 at 15.0 m/s.
