1) what kind of energy is gained when your roller coaster goes uphill?
2) based on your observations, what is the relationship between potential and kinetic energy?
3) if friction was completely removed from the track, what affect would this have on the roller coaster ride?
4) 4) why does the number of carts matter when designing a roller coaster track ?
(hint: pe = mass x gravity x height and ke – ½ mass x velocity ^2)

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?

Part of a control linkage for an airplane consists of a rigid member cb and a flexible cable ab. if a force is applied to the end b of the member and causes it to rotate by θ = 0.5°, determine the normal strain in the cable. originally the cable is unstretched.
