None of the above
5. If you toss a ball "horizontally" from one wall to an opposite wall inside an accelerating spaceship in deep space, defining "up" as the direction of acceleration, the ball will hit
a.
below its straight-line path.
b.
above its straight-line path.
c.
right the opposite point on the straight line
d.
the ball will not hit the wall, as it will be weightless and afloat.
