Cart A$,$ weighing $390$ lbs $,$ has an initial velocity of $15f\frac{t}{s}$ at the position shown in figure. If the cart has a constant rolling resistance of $10$ lb $,$ determine the spring deflection and the location of the cart with respect to its initial position when it comes to rest on the horizontal surface. The spring constant is $300l\frac{b}{i}n.$
