Explanation:
you made an error while putting the unit of velocity
acceleration = change in vel in time
a = (∆v/t)
the initial vel (u) =0m/s
the final vel (v) = 5,500m/s
time (t) = 8min + 30sec = 480 + 30
510s
a = (5,500 - 0)/510
5,500/510
a = 10.78m/s²
Answer:
(a)
(b)
Explanation:
<u>For Earth we have:</u>
- mass of earth,
- radius of earth,
- orbital radius,
- period of rotation,
- period of revolution,
(a)
Angular momentum,
∵...............................(1)
For a particle of mass m moving in a circular path at a distance r from the axis,
&
Putting respecstive values in eq. (1)
To model earth as a particle is reasonable because the distance between the sun and the earth is very large s compared to the radius if the earth.
(b)
For a uniform sphere of mass M and radius R and an axis through its center,
using eq. (1)
