a. Of course, one way for athlete 1 to overtake athlete 2 is for him to accelerate (that is, if v2 > v1). But since the given are constant speeds, surely v2 MUST BE LESS THAN v1 in order for athlete 1 to overtake athlete 2, WITHOUT accelerating. b. Recall that the distance ...

Math (College Pre-Cal)
since f(x) = e^(4-7x) f(g) = e^(4-7g) = e^(4-7lnx) = e^4 / e^(7lnx) = e^4/x^7

The exaust temp would be zero K. The engine would be at the same temperature it started at (probably O K, the exaust temperature) It could not vibrate, that takes energy.

All of your math is correct except that h is just 36.7 because the bungee is attached to his feet not halfway up his body. Therefore his potential energy has to be measured to that point. Then you get mgh=1/2kx^2 k=(2mgh)/x^2 k=(2*93.1*9.8*36.7)/9.3^2 = 774.29 N/m
