Day 111: Reference FramesPosted: April 18, 2014
In this problem, students had first looked at what would happen if Gravity took place far away from any planets (to remove, well, gravity from the situation…) and she threw an oxygen tank at 3 m/s. In this portion, they were asked how the situation would change if both Sandra and the tank were moving at 4 m/s and she threw the tank in the opposite direction of the motion. The students really wanted the tank to be moving backwards. We had a great discussion about it.
