A Cue Ball A Uniform Solid Sphere Of Mass M And Radius R Is At Rest On A Level Pool Table The Ball Is Positioned At Z 2 (51.25 KiB) Viewed 90 times
A cue ball (a uniform solid sphere of mass m and radius R) is at rest on a level pool table. The ball is positioned at z = 0. A pool cue is used to give the ball a sharp horizontal hit at its midpoint, as is shown in (Figure 1). This results in an initial translational velocity VO in the +z-direction. The coefficient of kinetic friction between the table and the cue ball is Hk. As the ball slides along the table, it begins to rotate. Eventually, its angular velocity increases to the point where the ball rolls without slipping. In terms of m. R..vo, and acceleration of gravity g, calculate (a) the translational acceleration of the cue ball while it is sliding; (b) the angular acceleration of the cue ball while it is sliding: (c) the translational and rotational velocities of the cue ball as a function of time, while it is sliding; (d) the distance the cue ball travels before it begins to roll without slipping.
