Also, I found that velocity 1 = 21.16 m/s and velocity 2= 33.48 m/s How do I find v1 and v2 from there? Can you tell me the formula please?

Now I understand, except why would x1 be equal to 300 m?

How does it equal 1.27? I've been trying, but I just can't seem to figure it out.

I don't really understand what you mean by that; could you explain further?

Homework Statement Drag racing usually involves two cars racing each other over a set distance. Although distances range from 200 m to 1 km, the 400.0 m drag race is the most popular. This race tests a vehicle's acceleration and top speed. Data collected on a race by a dragster- Distance (m) |...

Nice to meet you!

Even IB students need help sometimes ;)

Thank you so much for your help!

Is this wrong? If so, how would I write this out?

I put double negatives on the denominator because the question says is "decelerates at -2.00 m/s2 [W] or -(-2.00 m/s2)"

So s2 divided by s2 cancels each other out and does not equal s4? Because acceleration is m/s divided by s

Do the units become m2/s2 divided by m/s2?

This is what i did- (5.00 m/s [W])2 - (10.0 m/s [W])2 / 2 * -(-2.00 m/s2 (-5.00 m/s)2 - (-10.0 m/s)2 / 4.00 m/s2 After this, what happens to the units? How do the s2 cancel each other out?

I don't know how to. The anwer I am getting is -18.75, and i don't think that's right.

true, I didnt know how to add the subscript on top. But can you help me answer this?
