Answer :
Final answer:
The force needed to give a 0.25 kg arrow an acceleration of 196 m/s² is 49 N.
Explanation:
The force needed to give a 0.25 kg arrow an acceleration of 196 m/s² can be determined using Newton's second law of motion, which states that force (F) is equal to the mass (m) of an object times its acceleration (a). In this case, the mass of the arrow is 0.25 kg and the acceleration is 196 m/s². Therefore, the force needed is:
F = m * a
F = 0.25 kg * 196 m/s²
F = 49 N
So, the correct answer is (b) 49 N.
