All you need to use here is, Newton's second law: 
$$\sum F = ma$$ where F is the force, m is the mass and a is the acceleration.

You're given 2/3 variables for both the questions, it's just plugging and chugging and a tad bit of algebra.

1 m/s = 1 N So if the force doubles the acceleration doubles, so number 1 is C
Number 2 is first you convert .25kg to 2.5N and then you get the answer D
