Homework Statement The position of a particle as a function of time is given by x = (6 m/s)t + (-2 m/s^2)t^2. Find the average speed from t = 0 to t = 1 s ---------------------------------------------------------------------------------------Also, how would I plot x versus t for t = 0 to t =...

I have figured it out. Thank you.

Thank you.

Yes. Would that be correct equation to use?

I am trying to solve a problem, which requires me to first find the acceleration using the equation v^2 = v0^2 + 2axΔx. Do I divide both sides by 2ax first? Any help or advice would be much appreciated.

As you walk to class with a constant speed of 1.65 m/s , you are moving in a direction that is 16.2° north of east. How much time does it take to change your displacement by 25.0 m east? I know that v0 = 1.65 m/s. Would I use the equation: x = (v0 cosθ)t?Any help or advice would be much...

You're right. I don't know what I was thinking! I did figure out that I needed to divide 7rpm by 60s and multiply that number by 471.948s, which gave to 55rev. :smile:

Yes, I failed to mention that. Thank you for your help. :smile:

How do I go about solving for the powers of p and q to make the equation dimensionally consistent? Any help or advice would be much appreciated! :smile:

NASA's Cassini mission to Saturn released a probe on December 25, 2004, that landed on the Saturnian moon Titan on January 14, 2005. The probe, which was named Huygens, was released with a gentle relative speed of 31 cm/s. As Huygens moved away from the main spacecraft , it rotated at a rate of...
