A spring of force constant k is compressed by a distance x from its equilibrium length. (a) Does the mass of the spring change when the spring is compressed? Explain.
(b) Find an expression for the change in mass of the spring in terms of k, x, and c.
(c) What is the change in mass if the force constant is 2.0 × 102 N/m and x = 15 cm?

Acar is going 5m/s around a bend with a radius of 10m/s why is the accelerant?

The force will determine the acceleration.
