AI Thread Summary
The discussion revolves around calculating the initial velocity of a car based on the length of its skid marks, which are 9.60 km, and its deceleration of -2.00 m/s². Participants emphasize the importance of providing personal input when seeking help, as it fosters learning rather than simply providing answers. The original poster eventually figures out the solution, acknowledging their inexperience in physics. The conversation highlights the collaborative nature of the forum, encouraging users to engage actively with the material. Overall, the thread underscores the balance between assistance and self-learning in educational discussions.

The skid marks left by a decelerating car were 9.60 km long. If the car's acceleration was -2.00 m/s^2, what was the car's initial velocity?


any help is much appreciated!

Welcome to PF!

What have you tried so far? Are you sure the skid marks are 9.6 km long?
 
thanks!

yep, the skid marks are that long. Its suppose to be a very fast car, lol.

That looks more like a rocket on wheels.
 
Fair enough. What have you tried so far then? On this forum you can't receive help without some input from yourself. We help with homework we don't do it for you. :smile:
 
lol, hey guys, i figured it out. i know i know, its probably the easiest question yall have seen, but its my 1st week in physics, lol.
 
oh ic kurdt, cool, i'll do that from now on.
 
No problem. It just helps the student learn rather than being handed things on a plate and not learning anything. If you have any more questions please come back. :smile:
