Question 9 (2 points) 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? wwwwwww. t=3T/4 t=0 t=T/2 22 V t=T/4 3 t=T/4

A 0D t=3T/4 7 t=3T/4 -A Position 3. Position 1. V 6 8 t=T/2 t=T 91 O v 22 u t=T/4 3 t=T/4 3 +A DX

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