Acceleration, a = (v - u) / t
Initial Velocity, u = 30 m/s
Final Velocity, v = 23 m/s
time t = 2.00 seconds
a = (23 - 30) / 2
a = -7 / 2 = -3.5 m/s2
So the acceleration is negative, which means it is a deceleration of 3.5 m/s2.
Answer:
For it is a Globular Cluster
Explanation:
These Globular clusters are not considered to be a galaxies because they bond gravitationally to orbiting galaxies like the Milky Way and their masses are relatively small.
In globular clusters, the stars are closed together and they are like 70times closer to one another in their solar neighbourhood.
A globular cluster is a spherical collection of stars that orbits a galactic core. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes, and relatively high stellar densities toward their centers.
