If the only force exerted on a star far from the center of the Galaxy (r = 7.40 ✕ 1020 m) is the gravitational force exerted by

lina2011 [118]

Answer:

The value is $v = 1.309*10^{5}\ m/s$

Explanation:

The radius is $r = 7.40 *10^{20} \ m$

The mass of the ordinary matter is $M_{rod} = 1.90 *10^{41}\ kg$

Generally the speed of the star is mathematically represented as

$v = \sqrt{\frac{G * M}{r} }$

Here G is the gravitational constant with a value

$G = 6.67384 * 10^{-11}$

$v = \sqrt{\frac{6.67384 * 10^{-11} * 1.90 *10^{41}}{7.40 *10^{20}} }$

=> $v = 1.309*10^{5}\ m/s$

<h3>What is Projectile motion ?</h3>

Projectile motion is the motion of an object thrown (projected) into the air.

After the initial force that launches the object, it only experiences the force of gravity. The object is called a projectile, and its path is called its trajectory

A projectile can be a thrown ball, a bullet or a springboard diver ... Except for air resistance, the forward velocity of any projectile is constant and is equal to the initial velocity when it was released.
