Answer :
The force which is needed to give a 0.25kg arrow with an acceleration of 196 m/s² is 49N. Thus, the correct option is B.
What is Force?
Force can be defined as the push or the pull on an object with the mass that causes it to change its velocity. Force is an external agent which is capable of changing a body's state of rest or motion. It is a vector quantity which has both a magnitude and a direction.
The force required to give a 0.25kg arrow an acceleration of about 196 m/s² can be calculated through the formula:
f = m × a
where, f = force of an object,
m = mass of the object,
a = acceleration of the object.
f = 0.25kg × 196 m/s²
f = 49N
Therefore, the correct option is B.
