A particle of mass 4 kg is excuting S.H.M. Its displacement is given by the equation y=8 `cos[100t +pi//4] cm`. Its maximum kinetic energy is,

A

128J

B

64j

C

16j

D

32j

Text Solution

Verified by Experts

The correct Answer is:
a
` m= 4kg, Y=8cos[100t+pi//4] cm`
v=8
` KE=1/2mV^2=1/2xx(4)(8)^2= 128 j`
