Answer:
Explanation:
Given
mass of objects m is 2.8 kg
objects is away from axis of rotation
angular velocity
moment of inertia of stool and student is
New distance of objects
conserving Angular momentum
Initial Angular momentum
For Second case
From that list, the only unit of mass is the "gram".
But that isn't the SI base unit of mass.
The base unit is the kilogram.
Constellations are based off of many Greek and Roman fables. Many of their gods and beliefs are pictured in the stars, which is where we get most of our constellations. Hope this helps!

Answer:
8 m/s²
Explanation:
α = 0.04 rad/s²
w = 0.2 rad/s
t = ?
α = w/t
===> t = w/α = 0.2/0.04 = 5 sec
v = wr = 0.2 × 200 = 40 m/s
the net acceleration a = v/t = 40/5 = 8 m/s²
