The solar radius is the distance between the core and the outer edge of a star.

The solar radius is the distance between the core and the outer edge of a star. Betelgeuse, Rigel, and Polaris all have large solar radii. Sirius B, Epsilon Eridani and Barnard’s Star all have small solar radii. What is the relationship between the solar radius and the brightness of stars?

0.28 J

Explanation:

Let the mass of the object is 0.5 kg

The maximum velocity of the object is 1.06 m/s.

We need to find the kinetic energy at that time. It is given by :

K=\dfrac{1}{2}mv^2\\\\=\dfrac{1}{2}\times 0.5\times (1.06)^2\\\\K=0.28\ J

So, the required kinetic energy is equal to 0.28 J.
