A 250-g оbject cоnnected tо а light spring with а spring constаnt of 1.00 N/m sits on a frictionless horizontal table. Suddenly, the object is knocked by a force causing it to move towards right and then vibrate back and forth with an amplitude of 10.0 cm as shown in the drawings. Which curve below correctly describe the variation of the spring force on the mass as a function of time?
