SHMHard
Question
Acceleration a versus time t graph of a body in SHM is given by a curve shown below. T is the time
Options
A.
B.
C.
D.
Solution
x = A cosωt
K.E. =
k(A2 − x2)
=kA2 sin2ωt
=
kA2 
=
1 − cos2ωt)
Frequency of K.E. is double of acceleration.
K.E. =
k(A2 − x2)=
kA2 sin2ωt=
kA2 =
1 − cos2ωt)Frequency of K.E. is double of acceleration.
