The minute hand on a watch is 2.0cm in length. What is the displacement vector of the tip of the minute hand? from 8-8:20 am. Express vector DeltaR in the form DeltaR_x, DeltaR_y, where the x and y components are separated by a comma. I thought i had it with the answer of 3.4 cm, but they want it in x and y components its a circle! My book has nothing for me and im significantly lost.
