A 500 kg cart (including the passenger) coasts down a 37° incline that is 50.0 m long. The cart is stopped by compressing a spring at the end of the incline. The effective coefficient of friction between the cart and the incline is 0.400. While stopping, the magnitude of the acceleration should not exceed 10g. Choose a spring (essentially choose a spring constant) and an appropriate stopping distance so that this condition is satisfied.

This is a fascinating problem. I have worked out what I think is the correct solution. You will find the analysis (but not the numerical answer) here:

Please check the math to make sure I did it right, I will do the same and edit it if I find an error--so check back tomorrow.
