1) A pebble of mass 0.50gm is stuck on the wheel of bicycle, marking a spot on the tire. When the pebble reaches the apex of its path, it is moving AB mph relative to the axle. The radius of the tire is 8 in. What are the linear momentum relative to the wheel axle for the pebble in (gm*m)/s
2) What are the angular momentum about the wheel axle for the pebble?
