Q1. Two bicycle tires are set rolling with the equivalent initial speed of 5.0 m/s along a long, straight road, and distance each travels before its speed is reduced by half is measured. One tire is inflated to a pressure of 40 {rm psi} and goes the distance of 17.7 m; the other is at 105 {rm psi} and goes the distance of 92.5 m. suppose that the net horizontal force is due to rolling friction only and take the free-fall acceleration to be g = 9.80 m/s^2.

Q2. What average force must be applied to a 0.45 kg ball travelling horizontally at the 30.8 m/s to bring the ball to rest in 0.23 seconds?
