This sounds like a fun problem! 0.69 m/s This is a tricky problem. About 140 kg 1.10 m/s (East) 4.40 m/s (East) (Note: use equations given in problem 30.) -3.00 m/s and 2.0 m/s The balls simply exchanged velocities, this is always true for objects of equal mass in a 1- D elastic collision. 0.35 m and 1.4 m Vertical 0.16 m horizontal 0.94 m 1.08 x 10^-22 kg m/s at 150 degrees from the electron 33.0 degrees at 0.808 m/s |
