Question

A simple pendulum of length 1 m is allowed to oscillated with amplitude 2o. It collides elastically with a wall inclined at 1o to the vertical. Its time period will be : (use g = π2)

Options

A.2/3 sec
B.4/3 sec
C.2 sec
D.None of these

Solution

Time period for half part : T = = 2sec.
So 2o part will be cornered in a time t = = 1 sec.
For the left 1o part : θ = θ0 sin (ωt)1o = 2o sin = π × t ⇒ t = 1/6 sec.
Total time = + 2t ⇒ 1 + 2 × = 1 + sec.
