I have an assignment question, it states: Surprisingly little advantage is gained by getting a running start in a downhill race. To demonstrate this, claculate the final speed of a skier who skis down a hill 80-m-high with negligible friction (a) if her initial speed is zero; (b) if her initial speed is 3.0 m/sec. [this final speed found in part (b) is larger than in part (a), but by far less than 3.0 m/sec!]
