Two bicycle tires are set rolling with the same initial speed of 3.80 m/s 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 psi and goes 18.6m ; the other is at 105 psi and goes 92.6m . Assume that the net horizontal force is due to rolling friction only.
What is the coefficient of rolling friction (Uk) for the tire under low pressure?

What causes the formation of ocean currents?

The radius of a sphere is increasing at a rate of 9 cm/ sec. find the radius of the sphere when the volume and the radius of the sphere are increasing at the same numerical rate.
