W=mg
m = W/g = 390N/ 9.8 m/s^2 = 39.8 kg
some people round g to 10 m/s^2 and this will give answer of 39 kg, which is wrong
Answer:

Explanation:
The ball moves with constant velocity, so the distance it covers is given by:
where
v=6 m/s is the ball's velocity
t=50 s is the time
Substituting these numbers into the equation, we find
As we sit in a chair, Action force will be only in one direction and that direction would be downward only.
In short, Your Answer would be Option A
Hope this helps!
