g a mass of 1.3 kg is pushed horizontally against a massless spring with a spring constant of 58 n/m until the spring compresses

ExtremeBDS [4]

Answer: $1.102\ J$

Explanation:

Given

Mass $m=1.3\ kg$

Spring constant $k=58\ N/m$

Compression in the spring $x=19.5\ cm\ or\ 0.195\ m$

When the mass leaves the spring, the elastic potential energy of spring is being converted into kinetic energy of mass i.e.

$\Rightarrow \dfrac{1}{2}kx^2=\dfrac{1}{2}mv^2\\\\\Rightarrow \dfrac{1}{2}\cdot 58\cdot (0.195)^2=\dfrac{1}{2}mv^2\\\\\Rightarrow \dfrac{1}{2}mv^2=1.102\ J$

The kinetic energy of the mass is 1.102 J.
