Question1

Two bicycle tires are set rolling with the same initial speed of 4.00m/s along a long, straight road, and distance each travels before its speed is reduced by half is measured. One tire is magnified to a pressure of 40 psi and goes the distance of 18.1m; other is at 105 psi and goes the distance of 92.4m. suppose that a net horizontal force is due to rolling friction only and take a free fall acceleration to be g = 9.80m/s2

Question2

Jean camps by a wide river and wonders how wide it is. She spots large rock on the bank directly across from her. She next walks upstream until she judges that an angle between her and the rock, that she can still see clearly, is now at an angle of 30 degrees downstream. Jean measures her stride to be about one yard long. Distance back to her camp is 120 strides, about how far across, both in yards and in meters, is river?
