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 front is defined as a "boundary" that separates two masses of different air densities. I am not entirely sure, but I think the answers are either C or D, but I'm mostly convinced it's option D.
Sounds like you've been given some unnecessary information.
<span>The linear velocity "v" and angular velocity "w" of something in circular motion of radius "R" are related as; </span>
<span>v = Rw </span>
<span>You are given v= 15 m/s and R = 3 m , so just solve for "w".</span>
