Answer:
The steps are outlined in the explanation below.
Explanation:
The average velocity is derived midpoint from the initial to the final velocity. Here is the proof:
Find the total displacement:
let the displacement be given by the letter s
Then since the average velocity is defined as:
where t = final time
t₀ = initial time
v = final speed
v₀ = initial time
where x denotes the position, then
where v = and dx = change in distance with respect to time.
Answer:
Explanation:
The angular momentum of the pulsar is given by:
where
is the mass of the pulsar
is the radius
is the angular speed
Given the period of the pulsar, , the angular speed is given by
And so, the angular momentum is
