Question

On your first trip to Planet X you happen to take along a 295g 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 31.8cm . You then pull the mass down 5.50cm and release it. With the stopwatch you find that 10.0 oscillations take 14.8s . Can you now satisfy your curiosity?

Explanation / Answer

An air-track glider is attached to a spring. The glider is pulled to the right and released from rest at t=0 s. It then oscillates with a period of 2.05 s and a maximum speed of 58.0 cm/s. 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)
