A 250-g object connected to a light spring with a spring constant 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 drawing. In which positions does the spring-mass-system have maximum potential energy? wwwwwwwww t=3T/4 t=3T/4 16 -A t=0 t=T/2 t=T 64 V 8 0 V 2 $4 ע t=T/4 3 t=T/4 3 +A X

V > < V Position 5. Position 7. Position 1. Position 8. Position 3. Position 9. Position 6. Position 2. Position 4. 1. Yes. 2. No.
