MHT CET 2026 Physics question
A mass attached to a spring performs S.H.M whose displacement is x = 3 x 10 cos2t. The time taken to obtain maximum speed for the first time is (in s)
Answer: (C)
Solution
Compare with : rad/s, so the period is s. At the mass is at the extreme position () with zero speed. The speed is maximum when ,
