A large fake cookie sliding on a horizontal surface is attached toone end of a horizontal spring with springconstant k = 420 N/m; the other endof the spring is fixed in place. The cookie has a kinetic energy of22.0 J as it passes through the spring's equilibrium position. As the cookie slides, a frictional force of magnitude 9.00 N acts onit. (a) How far will the cookie slidefrom the equilibrium position before coming momentarily torest? (b) What will be the kineticenergy of the cookie as it slides back through the equilibriumposition?
