A 12 gram coin is placed 6cm from the center of a vinyl record on a record player. A frictional force of 0.0125N acts on the coin causing it to go around in a circle. a) In what direction is the acceleration of the coin?
b) What is the magnitude of the acceleration of the coin?
c) What is the coin’s speed?

what is the actual question though?

the tires are rotating at 0.434 rpmlinear speed=45 m/sdiameter=0.550 mradius=0.275 mnow v= rωω= v/rω=45/0.275ω=163.6 rad/sω=163.6 rad/s (1rev/2π rad) (60s/1m)ω=1563 rpm

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
