Elevators are great places to think about physics, including Newton's laws. Here are a couple questions: A. The elevator accelerates upward at 3 m/s per second. What do you feel with this acceleration? What's the force on you? B. To understand the concept of tension better, you hang two masses of 3 kg each from the ceiling with two cords according to the set-up shown in Figure 1. What would the tension readings be in those two cords if the elevator accelerates upward at 3 m/s per second
