Assignment: 1. A thermometer reading 75" F is taken out where the temperature is 20" F. The reading is 30" F 4 minutes later. Find a) the thermometer reading 7 minutes after the thermometer was brought outside, and b) the time taken for the reading to drop from 750 F to within half a degree of the air temperature or 20.50 F. 2. A 45 N weight is projected downward with an initial speed of 4.6 m/s. If the air resistance is proportional to the speed and if the limiting speed is double the initial speed, how far has the body traveled when it has reached a speed of 6 m/s
