Abike is pushed with a net force of 2.5 n, and it accelerates 0.5 m/s2. if you pushed the bike with twice that amount of net force, the acceleration would be

0.25 m/s2 because net force and acceleration have an inverse relationship.

0.5 m/s2 because the net force and acceleration do not affect each other.

more than 0.5 m/s2, but less than 1 m/s2 because net force and acceleration do not have a proportional relationship.

1.0 m/s2 because net force and acceleration have a proportional relationship.
