Answer:
See the answers below.
Explanation:
To solve this problem we must use the following equation of kinematics.
where:
y - yo = Fall distance [m]
Vo = initial velocity = 0 (dropped)
t = time = 6.5 [s]
g = gravity acceleration = 9.8 [m/s²]
Now replacing:
The question is related to the distance between the points where the ball was dropped and the ground.
The variables used are gravitational acceleration, time, fall distance, initial velocity.
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
