Question
A particle executes simple harmonic motion of amplitude 16cm and time period 2.4s. What is the minimum time taken by the particle to move between two points 8cm on either side of mean position?
Solution
The position of the particle executing simple harmonic motion is given by
Let the position of particle be +8 cm at t1 and -8cm at t2.
Therefore the time taken by particle to move between two points 8cm on either side of mean position is,
The minimum time is 0.4s.
