Crate is being lowered by a crane at a constant speed of 2 m/s when a ball falls out of the hole in the crate, it hits the floor 10s before the crate. Find the height of the crate when the ball fell out of the crate.
How do I find the height?
All formulas gave me 20 as the height.. which is wrong.
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
2- the distance travelled after the finish line
3- the acceleration of the cyclist
4- the average speed of the cyclist from the starting to finish
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?
