Depth of a Well One method for determining the depth of a well is to drop a stone into it and then measure the time it takes until the splash is heard. If d is the depth of the well (in feet) and t1, the time (in seconds) it takes for the stone to fall, then
How deep is the well if this total time is 3 s?

- Force If you have ever ridden on a chair lift at a ski area and had it stop, you know that the chair will pull down on the cable, dropping you down to a lower height than when the chair is in motion. Figure 19 shows a gondola that is stopped. Find the magnitude of the tension in the cable toward each end of the cable if the total weight of the gondola and its occupants is 1,850 pounds.arrow_forwardYOUR TURN Find dy if y=300x23,x=8, and dx=0.05.arrow_forward
