A rotating satellite has the same angular velocity as the earth. If the satellite is 5x10^7 m from the center of the earth, what
1 answer:
We will want to be using radians for this question so that we can calculate arc lengths easily.
The angular velocity of the earth is
The satellite tangential velocity is the distance from the earth times the angular velocity, which is
For meters per second, we divide by the number of seconds in an hour, which is 3600:

Answer:
Part a)
Part b)
Part c)
Explanation:
Part a)
As we know that initially the grass hopper is at rest at the ground position
Now the acceleration is given as
distance of the legs that it stretched is given as
so we have
Part b)
time taken to reach this speed is given as
Part c)
as the grass hopper reach the maximum height its final speed would be zero
so we will have
