My answer -
I believe that the answer is (A).
P.S
Happy to help you have an AWESOME!! day
Answer:

Explanation:
The horizontal distance covered by the ball in the falling is only determined by its horizontal motion - in fact, it is given by

where
is the horizontal velocity
t is the time of flight
The time of flight, instead, is only determined by the vertical motion of the ball: however, in this problem the vertical velocity is not changed (it is zero in both cases), so the time of flight remains the same.
In the first situation, the horizontal distance covered is

in the second case, the horizontal velocity is increased to

And so the new distance travelled will be

So, the distance increases linearly with the horizontal velocity.
Potential energy is energy stored in an object. kinetic energy is energy of motion

Weight equals mass times gravitational acceleration=400N, so mass=400/9.8=41kg approx.
