Homework Statement A bowler throws a bowling ball of radius R = 11 cm down a lane. The ball slides on the lane, with initial speed vcm,0 = 6.0 m/s and initial angular speed 0 = 0. The coefficient of kinetic friction between the ball and the lane is 0.34. The kinetic frictional force fk acting...

The angular momentum of a flywheel having a rotational inertia of 0.200 kg·m2 about its axis decreases from 3.00 to 1.800 kg·m2/s in 1.80 s. (a) What is the average torque acting on the flywheel about its central axis during this period? N·m (b) Assuming a uniform angular acceleration...

Yeah, i just rechecked my work and everything at it worked out. You freaking rock man! Thanks for all the help!

Yeah, i plugged the answers into the site and it did not accept them as correct. Within the hitch hiker part, the accel would be zero (according to the a = v^2/r) because the v is zero at the bottom. For the hitch hiker/top of the wheel part, i calculated the accel to be 2.53E3 m/s^2, which is...

Thanks for the help, it worked the the two on the first part but it didn't work for the second set of two.

hey guys, i was wondering if anyone could explain how to find the linear acceleration of a point at the top and bottom of a wheel. the homework problem is as follows (just so you know the context, i don't want the answers, i want to know how to go about this.): Consider a 61 cm diameter tire on...
