Two bicycle tires are set rolling with the same initial speed of 3.70 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 a distance of 17.8 m ; the other is at 105 psi and goes a distance of 93.3 m . Assume that the net horizontal force is due to rolling friction only and take the free-fall acceleration to be g = 9.80 m/s2 .

a)What is the coefficient of rolling friction μr for the tire under low pressure?

1) A cylinder of Mass M and radius R, and initial speed V, starts rolling up an incline of angle theta relative to horizontal. Assuming no slipping, how high up does the cylinder get? 2) teeter/totter a) Peewee has mass m and his big buddy Delilah has mass 2m. If Peewee sits at one end of a uniform teeter totter of length L and mass M, how far from the central pivot should Delilah sit (ie on the other end)...

A 10 g marble slides to the left at a speed of 0.4 m/s along a frictionless surface. It has a head-on, elastic collision with a larger, 30 g marble sliding to the right at 0.2 m/s. Since the collision is head-on, all motion is along the x-axis. a. Find the total kinetic energy AND the total momentum before the collision b. The marbles bounce off each other elastically. Each marble has a different velocity after the collision. The lighter...

A trooper is moving due south along the freeway at a speed of 33 m/s. At time t = 0, a red car passes the trooper. The red car moves with constant velocity of 45 m/s southward. At the instant the trooper's car is passed, the trooper begins to speed up at a constant rate of 1.5 m/s2. What is the maximum distance ahead of the trooper that is reached by the red car? m
