Question
A toy roller coaster cart is launched by first compressing a spring, then being released to
travel up the track. Assume that:
•The spring compresses by a maximum of 0.14 m
•The mass of the cart is 0.24 kg
•The work done by friction is 0.29 J
•The height of the first hill is 0.75 m
What spring constant is necessary to get the cart to the top of the first hill, traveling at 0.9 m/s?
Draw a sketch of the system with relevant zero reference points and an LOL diagram
