A bike wheel with a radius of 0.1 m and mass 2.0 kg is spinning at 18 rad/s. A block is pushed against the top of the
wheel with a force N of 20 N. The coefficient of kinetic friction between the block (neglect the block mass) and the
wheel is 0.5. How long does it take for the wheel to stop?

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
