Thank you for all your help. I unfortunately wasn't able to check this again before the hmwk was do and wasn't able to figure it out. But thanks anyways!

For "A" is the equation you are referring to V_i_=sqrt(k/m)x_i_? or is it v_f_=v_i_-WAcos(Wt)? As far as "B" goes, that is what the question asks. I copied the question directly from mastering physics.

Homework Statement A 2.55 kg ball is attached to an unknown spring and allowed to oscillate. The figure shows a graph of the ball’s position x as a function of time . (A)What is the maximum kinetic energy of the vibrating ball? give answer in joules (B)When does it occur? (give answer in cm)...

I got it! Thank you so much! Wow I didn't think it could have been that easy! Thanks again!

This is where I get stuck. I know that in order to accelerate, the rocket must overcome this new "g" value, but I don't know what equation I would use to figure out the rocket's acceleration.

Thanks. Sorry it took so long to respond I have been at work all day. Anyways, with using 1.50m as the length and the shorter period of 1.26 seconds, I get a new value of "g" as 37.3 m/s^2

yeah you are right. i did do something qrong. i redid it and got 1.50

Homework Statement An astronaut notices that a pendulum which took 2.46 seconds for a complete cycle of swing when the rocket was waiting on the launch pad takes 1.26 seconds for the same cycle of swing during liftoff. What is the acceleration of the rocket?(Hint: Inside the rocket, it appears...
