A)
B)
C)
D)
Correct Answer: C
Solution :
Key Idea: Body start from rest hence initial velocity is zero. From equation of motion, we have \[\frac{1}{2\pi }\sqrt{\frac{k}{m}}\] where v is final velocity, u is initial velocity, a is acceleration and t is time. Since, body starts from rest u = 0 \[\frac{1}{2\pi }\sqrt{\frac{2k}{m}}\] \[\frac{1}{2\pi }\sqrt{\frac{3k}{m}}\] Which is general equation of parabola \[\frac{1}{2\pi }\sqrt{\frac{k}{m}}\], hence graph is parabolic and is symmetrical along s-axis.You need to login to perform this action.
