Acoin of radius b and mass m rolls on a horizontal surface at speed v. if the plane of the coin is vertical the coin rolls in a straight line. if the plane is tilted, the path of the coin is a circle of radius r. find an expression for the tilt angle of the coin a in terms of the given quantities.(because of the tilt of the coin the circle traced by its center of mass is slightly smaller than r but you can ignore the difference.)

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
