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

I said 49N because F = MxA.
Am I correct?
Yes, you are correct. To determine the force needed to give an object an acceleration, you can use the equation F = m x a, where F is the force, m is the mass of the object, and a is the acceleration.
In this case, the mass of the arrow is given as 0.25 kg and the acceleration needed is given as 196 m/s^2.
Plugging these values into the equation F = m x a, you get F = 0.25 kg x 196 m/s^2 = 49 N.
Therefore, the correct answer is B. 49 N.
