I have a group depending on me.. and I have no idea where to begin with these problems.... they're additional calculations connected with a rollercoaster project we're doing... our average friction is .0212 N if that is needed.... someone please direct me to some solution you have no idea how much I would appreciate it..(adsbygoogle = window.adsbygoogle || []).push({});

i. if the spring constant is 2000 N/m, how far will the spring have to compress to bring the caoster to a stop? (Assume the weight of the coaster and passengers to be 45,000 N)

ii. If the spring dissipates half the available energy as heat, how far will your ride go (after released by the spring) before it stops or begins to roll foward? Don't forget friction.
