A particle executes SHM with amplitude 5 cm. When its displacement from the mean position is 3 cm, its speed is 16 cm/s. If the angular frequency is N rad/s, find N.

G1 Physics · Accepted Answer

Use v = ω√(A²−x²). Substitute A = 5 cm, x = 3 cm, v = 16 cm/s. Then, 16 = ω√(25−9) = 4ω. Therefore, ω = 4 rad/s. Hence, N = 4.
