A steel ball rolls down a ramp and collides with a marble, as in the video. The marble is slightly smaller and quite a bit less massive than the ball.
If they both experience the same force, which will have the greater acceleration?
The marble would have the greater acceleration because big things accelerate slower than small things. The steel ball is much heavier than the marble and it takes it more force to accelerate. If the two collide, the marble would accelerate faster, because it has less wieght and the force from the steel ball would create a faster acceleration.

If the forces were exerted during identical time intervals, which would have the greater change in velocity?

Well if the marble accelerates faster than that also means its velocity changes faster.
