Question
A spring block system is executing SHM with angular frequency of 1 rad/sec and has an amplitude of 2m. Find the maximum kinetic energy of the system.Given mass of the block is 2 kg.
Answer: Option B
:
B
KE=12m(ω√A2−x2)2
K.E. is max at x = 0 (mean position)
⇒KEmax=12m(ω2A2)
=122(22)
KEmax=4J.
