Neutron is commonly used to initiate a fission chain reaction.
Speed of Ferry is towards North with magnitude 6.2 m/s
Here if we assume that North direction is along Y axis and East is along X axis then we can say
Now a person walk on ferry with speed 1.5 m/s towards east with respect to Ferry
so it is given as
also by the concept of relative motion we know that
now plug in all values in it
now if we need to find the speed of the person then we need to find its magnitude
so it is given as
A 4x100 relay is where 4 people run 100 meters and a 4x400 relay is where 4 people run 400 meters
Answer:
20 m/s westward
Explanation:
Taking eastward as positive direction, we have:
is the velocity of Bill with respect to Amy (which is stationary)
is the velocity of Carlos with respect to Amy
Bill is moving 5 m/s eastward compared to Amy at rest, so the velocity of Bill's reference frame is
Therefore, Carlos velocity in Bill's reference frame will be
and the direction will be westward (negative sign).
