🤓 Based on our data, we think this question is relevant for Professor Sitz's class at TEXAS.

Solution: Margie (of mass 41 kg) and Bill (of mass 65 kg), both with brand new roller blades, are at rest facing each other in the parking lot. They push off each other and move in opposite directions, with Margie moving at a constant speed of 18 ft/s. At what speed is Bill moving? 1. 12.5735 2. 8.4 3. 9.0 4. 13.871 5. 7.61905 6. 8.65574 7. 11.9118 8. 11.3538 9. 10.2857 10. 9.53333
