Thanks skeeter. That helped, I got the right answer.
I got more questions I do not understand.
Edit: I forgot to specify what I'm actaully stuck on, the 5th question, where the skater is 2 seconds earlier than the cyclist. I'm just wondering how to put it on the graph. So, I assume SKATER:
, is that right?
A cyclist, passes the starting line
The cyclist reaches the finish at
What I have so far:
1- the distance of the starting from the finish line
correct
2- the distance travelled after the finish line
correct
3- the acceleration of the cyclist
correct
4- the average speed of the cyclist from the starting to finish
|v{avg}| = (260 m)/(22 s)
5- A skater passed the starting line 2 seconds before cyclist. Skater is travelling at a constant speed of
. Who wins the race and how much?
t = 260/11 = 23.6 s ... but he got a 2 second headstart, so the skater crosses the finish line at t = 21.6 s relative to when the cyclist started.
