A 0.5-kg block slides among a horizontal frictionless surface at 2 m/s. It is brought to rest by compressing a very long spring of spring constant 800 N/m. What is the elastic potential energy stored in the block-spring system when the block is brought to rest?
Homework Answers
Here ,
as the energy stored in the spring is equal to the initial kinetic energy of the block when the block comes to rest
elastic potential energy stored in the block-spring system = 0.50 * m * v^2
elastic potential energy stored in the block-spring system = 0.50 * 0.50 * 2^2
elastic potential energy stored in the block-spring system = 1 J
the elastic potential energy stored in the block-spring system is 1 J
