Is there a relationship between how many sit-ups you can do and how fast you can run 40 yards?

a. The regression equation is 6.71 - 0.024x. Find the predicted time in the 40-yard dash for a subject who can do (i) 10 sit-ups, (ii) 40 sit-ups.

b. Interpret the y-intercept and slope of the equation in (a), in context.

c. Based on the slope in (a), is the correlation positive, or negative? Explain.

A record of travel along a straight path is as follows.
1. Start from rest with constant acceleration of 2.71 m/s^2 for 15.1 s.
2. Constant velocity for the next 3.47 min.
3. Constant negative acceleration -9.68 m/s^2 for 3.39 s.

a) What was the average speed for leg 3 of the trip in m/s?
b) What was the average speed for the complete trip in m/s??

I tried this problem and I keep getting it wrong, I have no idea what I am doing wrong! Please help! THANKS!

This is due tonight and I DO NOT understand. How do you due this problem, and what is the answer?

"A freely falling object requires 1.90 seconds to fall the last 38.0 m before it reaches the ground. From what height did the object fall?"

This is not in my book. None of the formulas work because you have to know more variables than I am given. PLEASE help me.

A child throws a rock upwards with a speed of 40.0 m/s. At the end of 10 seconds, (a) where is the stone and (b) at what speed is the stone moving?

My answers came out to:

(a) 890 m

g(x) = 3 - x^2

g(t - 1)

______________________________...

heres what I did:

g(t-1) = 3 - (t-1)^2

"" = 3 - (t-1)(t-1)
"" = 3 - t^2 -t -t +1
"" = 3 - t^2 - 2t + 1
"" = -t^2 - 2t + 4
"" = t^2 +2t - 4

The answer in the book says it should be:
-t^2 +2t + 2
which would be the same as:
t^2 -2t -2

So where did I go wrong? I'm betting it has something to do with that "3 - " part.
