what force is needed to give a 0.25 kg arrow an acceleration of 196 m/s²?\n0.25 n\n49 n\n196 n\n748 n

Explanation:

Step1: Identify the formula

Use Newton's second - law $F = ma$, where $F$ is force, $m$ is mass and $a$ is acceleration.

Step2: Substitute values

Given $m = 0.25\ kg$ and $a=196\ m/s^{2}$. Then $F=0.25\times196$.

Step3: Calculate the force

$F = 49\ N$.

Answer:

B. 49 N
