Given:
w = z(t)= γ − β*t^2
Differentiating both sides with respect to t, we get:
α = z(t) = -2βt
Given: <span> γ = 5.35 rad/s and β = 0.810 rad/s3
</span>
so, For t = 3 sec,
angular acceleration = -2 * 0.810 * 3 = <span>-4.86</span>
A. Relaxing under a tree.
The parasympathetic nervous system is known as the “rest and digest” system. Activities that require as little movement as possible help the heart rate to slow down. The other activities would be associated with the Sympathetic nervous system which is known as the “fight or flight,” or when your heart rate is up and running.
Given mass= 1kg
Weight on earth = mg(gravity of earth) = 9.8N
weight on moon = mg(gravity of moon)= 1.62N
weight on outer space mg(gravity outer space = 0) = 0N
