Homework Statement
A device can be used to measure the speed of a bullet. The device consists of two rotating disks, separated by a distance of d = 0.850 m, and rotating with an angular speed of 95.0 rad/s. The bullet first passes through the left disk and then through the right disk. It is found that the angular displacement between the two bullet holes is 0.240 rad. From these data, determine the speed of the bullet.
Homework Equations
Angular displacement = arc length/radiusAngular velocity = angular displacement/time
The Attempt at a Solution
I attempted to set up an equation, but I simply couldn't.
