Homework H$\mathrm{.}3.$A

Given: The disk shown is rotating about its center with a constant rotation rate of $.$ Four slots

have been cut into the disk, and a particle in each slot has a constant speed of $v_{\text{r}\text{e}\text{l}}$ relative to the

disk. Each particle is at a distance of $R$ from the center of the disk.

Find: Determine the velocity and acceleration of each particle in the disk. Write your answers as

vectors.
