Answer #1
Answer: 
Explanation: There is a relation between the
linear velocity (
)
and angular velocity (
)
of an object with radius (
).
-----------------------------------------------
(1)
where, ''
is in the unit of m/s, ''
is in the unit of rad/s and ''
is in the unit of meters.
If the velocity,
is in the unit of (km/s) then, using the conversion formula,
(km/s)=(1/1000)*(m/s). So, from eqn 1,
----------------------------------------------
(2)
This is the required equation between (km/s) to (rad/s) of an
object with radius ''
in meter.
