A certain cable car in San Francisco can stop in 10 s when traveling at maximum speed. On one occasion,
the driver sees a dog a distance d in front of the car
and slams on the brakes instantly. The car reaches the
dog 8.0 s later, and the dog jumps off the track just in
time. If the car travels 4.0 m beyond the position of the
dog before coming to a stop, how far was the car from
the dog? (Hint: You will need three equations.)

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?
