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)

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_
