Suppose that the car is skidding as it decelerates : The front brake pads on your car wear out faster than the rear brake pads; in fact, some cars are specially designed with large front brake pads because of this. This results from the fact that when a car is breaking the magnitude of the friction for..

What is the period of the resulting oscillation : A 0.2 kg mass is attached to two springs by identical spring constants of 90 N/m and moves on a horizontal frictionless surface. The equilibrium length of each spring is 48 cm, so each is slightly stretched (to 50 cm) initially. The mass is then move..
