A quarter is spinning on its edge at 3.25 rev/s the quarter spins for 71s during this time the quarter slows down with constant angular accleleration. a piece of gum is stuck to the edge of 3.12cm radius of the spinning quarter.

a) what is the tangential accleration of the piece of gum

b) how many revolutions does the quarter make before coming to a stop

c)how many cm has the gum traveled during these revolutions

d) draw a forcce diagram
