Question 7 (3 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. wwwwwwww t=3T/4 7 t=3T/4 7 -A V 8- t=0 A t=T/2 5 t=T 0 V $4 V t=T/4 3 t=T/4 3 +A X
H chilar The above curve correctly describe the variation of the spring force on the mass as a function of time. NAL The above curve correctly describe the variation of the spring force on the mass as a function of time. AA र्णि -Elor The above curve correctly describe the variation of the spring force on the mass as a function of time. 1. Yes. 2. No.
