i found the amplitude to be 18.92. they want the gliders position at time 24 seconds. my answer of 5.35 and 5.4 are both wrong.

18.92cos(2pi(24)/2.05) this is what i did and i don't know what's wrong.

Problem 2:

On your first trip to Planet X you happen to take along a 165 g mass, a 40-cm-long spring, a meter stick, and a stopwatch. You're curious about the acceleration due to gravity on Planet X, where ordinary tasks seem easier than on earth, but you can't find this information in your Visitor's Guide. One night you suspend the spring from the ceiling in your room and hang the mass from it. You find that the mass stretches the spring by 31.5 cm. You then pull the mass down 6.60 cm and release it. With the stopwatch you find that 11.0 oscillations take 15.4 s.

their question is "can you now satisfy your curiosity"? answr in m/s^2

i don't really have a clue here
