Would the plank and the roller have the same acceleration why or why not?

A hole is to be drilled as shown by the circle. Using the part geometry shown below, indicate on the part sketch where locator(s) should be positioned according to the 3-2-1 principle. Use dashed lines to indicate locators on hidden surfaces. Also indicate where clamping force(s) should be applied using arrows. Use the minimum number of clamping forces.
