A pool player hit a ball with a mass of 0.25kg. The ball travels at a velocity of 15 m/s for 0.75 s until it hits the side of the pool table.

What additional information is required to determine the ball's weight?

A.

the value in m/s² of gravity acting on the pool ball

B.
the distance to the nearest pocket in the table

C.
the displacement of the pool ball

D.
the force of inertia acting on the pool cue

I'm going to say the answer is A, as weight is the force of gravity acting on an object, and we have the mass but no indication of gravitational force.
