Q. How many meters away is a cliff if an echo is heard 0.587 s after the original sound? Assume that sound traveled at 343 m/s on that day.

Q. Two bicycle tires are set rolling with the same initial speed of 3.90 along a long, straight road, and the distance each travels before its speed is reduced by half is measured. One tire is inflated to a pressure of 40 and goes a distance of 17.5 ; the other is at 105 and goes a distance of 92.3 . Assume that the net horizontal force is due to rolling friction only and take the free-fall acceleration to be = 9.80.
