publish a book in which he explained his heliocentric theory.

Explanation:

The heliocentric theory is the one according which the Sun is in the center of our Solar Sistem and the planets go around it.

Previously to this theory (before Copernicus) the prevalent theory was geocentrism accordind which it was the earth who stood in the center and all the other celestial bodies went around it.

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.
