Questions
The force constant of a weightless spring is 16 N/m. A body of mass 2.0 kg suspended from it is pulled down
through 5 cm and then released. The maximum kinetic energy of the system (spring + body) will be
detailed solution
Correct option is A
Maximum K.E. =12kx2 ∴ (K.E.)max=12×(16)×5×10−22 =2×10−2JTalk to our academic expert!
