Question
A particle executes SHM and its position varies with time as x = A sin wt. Its average speed during its motion from mean position to mid point of mean and extreme position is
Read 2 Solution.
total distance = A/2
total time = t (suppose)
then, A/2 = A sin wt
A/2 = A sin (2pi/T)t {because w= 2pi/T}
1/2 = sin (2pi/T)t
sin(pi/6) =sin(2pi/T)t
pi/6 = (2pi/T)t
t= T/12
avg. speed = total distance / total time
v = (A/2)/(T/6)
v= 3A/T
v= 3A/(2pi/w)
v= 3Aw/2pi
