In 1000 s (16.7 min), what is the uncertainty in position resulting from this uncertainty in velocity? Recall: distance = velocity x time, and Uncertainty in distance = (uncertainty in velocity) x time A) 1 km B) km C) 5 km D) 100 m E) 10 m On the homework you will have to use the real value for h and real masses, etc....
