The above spring block system does Linear SHM. It takes the block 10 sec to move from the mean position to extreme position that is 5m away. Which of the given options are correct?
None of these
Since the extreme position is 5m from the mean positions the amplitude is 5m.
It takes 10 sec to go from mean position to extreme position that is one fourth of the time period.
T=4×10sec=40sec
So angular velocity ω=2πT=2π40=π20
The equation of SHM, x=5 sin(π20t+ϕ0)
Lets say it starts from mean position ϕ0=0
x=5 sin(π t20)
