Assuming north as positive direction, the initial and final velocities of the ball are:

(with negative sign since it is due south)

the time taken is

, so the average acceleration of the ball is given by

And the positive sign tells us the direction of the acceleration is north.
#Case -1
If Pulling force is less than frictional force the object won't move .
#Case-2
If Pulling force is greater than frictional force then object will be .
In order to calculate friction force you need Limiting friction first .

u s is coefficient of static friction and N is normal reaction
Or

For number one, the answer is the first dash mark
And for number two, the answer is the 4th dash.
E=mc^2
hence m= E/c^2
= (3.6x10^26)/(9×10^16)
= 4x 10^9 kg
