Question

The force constant of weightless spring is 16 N/m. A body of mass 1.0 kg suspended from it is pulled down through 5 cm and then released. The maximum kinetic energy of the system (spring + body) will be:

• A. \( 2 \times 10^{-2} \, \text{J} \)
• B. \( 4 \times 10^{-2} \, \text{J} \)
• C. \( 8 \times 10^{-2} \, \text{J} \)
• D. \( 16 \times 10^{-2} \, \text{J} \)

Hint:

The maximum kinetic energy in a spring-mass system is equal to the potential energy stored in the spring at maximum displacement.

Answer 1

The Correct Option is A
