A sports car moving at constant speed travels 120 m in 5.1 s. If it then brakes and comes to a stop in 4.0 s, what is its acceleration? Express the answer in terms of g's, where g = 9.80 m/s2. (Take the positive direction to be the direction of travel.)

The problem is 3x^2 - 26 + 35 (We have to factor it!) So, I did the problem, but I'm not sure how to write the final answer. This is what my problem looks like so far: 3x^2 - 26 + 35 (3x^2-21x)-(5x+35) 3x(x-7)-5(x+7) and this is where I have the problem....

A 45 kg boy is holding a 12 kg pumpkin while standing on ice skates on a smooth frozen pond. The boy tosses the pumpkin with a horizontal speed of 2.8 m/s towards a 37 kg girl who catches it. The girl is also wearing ice skates. What are the final speeds...

I should add, the answer is given as 11.32s, I just don't know how to get there. Thanks again.

The acceleration increases at a constant rate, it does not remain constant. Thanks for replying, though. I'm still having trouble with it.

Err, I typed that wrong. The acceleration is in fact constant. The velocity on the other hand is increasing at a constant rate so at some point the velocity will be greater than the friction force can hold. I just can't put it all together.

(-2,1) and (2,1) are the vertices.

Wouldn't it be: x^2/4 - (y-1)^2/(9/5)=1 because that's what you get plug b^2 back into the original equation?

Thanks so much, but then do you plug in c back into the first point and tangent line and x-intercept to get the x and y coordinates and tangent line equation and x-intercept, respectively?

Can you explain to me how you found out the distance formula. Because how did you find out D^2 = c^4 + 2c^2 + 1 + c^2 - c^2 + 1 + (c^4-2c^2+1)/(4c^2)? I understand the first part with c^4 + 2c^2 + 1, but I don't understand how you got the second part.

And isn't (c^4-2c^2+1)/(4c^2) supposed to be (c^4+2c^2+1)/(4c^2)?

THANK YOU SO MUCH! :D
