An object of mass 2.0 kg is attached to a spring that has a spring constant of 62 N/m. Suppose the spring is stretched a maximum distance of 0.15 m before the object starts to move. What is mu_s, the coefficient of static friction

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?
