A particle is performing simple harmonic motion along x-axis with amplitude 4 cm and time period 1.2 sec. The minimum time taken by the particle to move from x =2 cm to x = + 4 cm and back again is given by
Time taken by particle to move from x=0 (mean position) to x = 4 (extreme position)
Let t be the time taken by the particle to move from x=0 to x=2 cm
. Hence time to move from x = 2 to x = 4 will be equal to 0.3 – 0.1 = 0.2 s
Hence total time to move from x = 2 to x = 4 and back again
