What force is needed to give a 0.25-kg arrow an acceleration of 196 m/s2? A. 0.25 N B. 49 N C. 196 N D. 748 N

The answer is B. 49 N

Force is equal to the mass of that object multiplied by its acceleration:

F = m * a

The unit of force is N = kg * m/s².

It is given:

m = 0.25 kg

a = 196 m/s²

F = m * a = 0.25 kg * 196 m/s² = 49 N
