Q.NO-28- two identical pendulums oscillate with a constant phase difference π/4 and same amplitude.if maximum velocity of one oscillation is v,then maximum velocity of second oscillation is-----?

Dear Student,
Please find below the solution to your problem.

If the phase difference is constant, they are moving with same frequency and w.
since maximum velocity Aw = v (given)
maximum velocity of other will still be v.
hence option 1 is correct.

Thanks and Regards
