a glider with mass m= 0.200 kg sits on a frictionless horizontal air track, connected to a spring with force constant k= 5.00 N/m . The glider is released from rest with the spring stretched 0.100 m.
A- What is the displacement x of the glider from its equilibrium position when its speed is 0.20 m/s? (You should get more than one answer.)
B- Explain why you get more than one answer?
