Q01 – AIPMT 2014 – The oscillation of a body on a smooth horizontal surface is represented by the equation
?=? cos⁡??
where ? = displacement at time t and ? = frequency of oscillation.
Which one of the following graph shows correctly the variation ‘a’ with ‘t’ ?

Q02 – AIPMT 1 2015 – A particle is executing SHM along a straight line. It velocities at distances x1 and x2 from the mean position are V1 and V2, respectively. Its time period is:
Q03 – AIPMT 1 2015 – When two displacements represented by ?_1=? sin⁡?? and ?_2=? cos⁡?? are superimposed the motion is
(A) simple harmonic with amplitude √(?^2+?^2 )
(B) simple harmonic with amplitude (?+?)/2
(C) not a simple harmonic
(D) simple harmonic with amplitude ?/?

Q04 – AIPMT 2 2015 – A particle is executing a simple harmonic motion. Its maximum acceleration is ? and maximum velocity is ?. Then, its time period of vibration will be:
(A) 2??/? (B) ?^2/?^2 (C) ?/? (D) ?^2/?

Q05 – NEET 2 2016 – A body of mass m is attached to the lower end of a spring whose upper end is fixed. The spring has negligible mass. When the mass m is slightly pulled down and released, it oscillates with a time period of 3 s. When the mass m is increased by 1 kg, the time period of oscillations becomes 5 s. The value of m in kg is:
(A) 9/16 (B) 3/4 (C) 4/3 (D) 16/9
Q06 – NEET 2017 – A particle executes linear simple harmonic motion with an amplitude of 3 cm. When the particle is at 2 cm from the mean position, the magnitude of its velocity is equal to that of its acceleration. Then its time period in second is:
(A) √5/? (B) √5/2? (C) 4?/√5 (D) 2?/√3
