Question

what force is needed to give a 4.5 kg bowling ball an acceleration of 9 m/s²?
0.5 n
2 n
36.5 n
40.5 n

Explanation:

Step1: Recall Newton's second law

$F = ma$ (where $F$ is force, $m$ is mass, $a$ is acceleration)

Step2: Substitute values

Given $m = 4.5$ kg and $a=9$ m/s², then $F=(4.5)(9)$

Step3: Calculate

$F = 40.5$ N

Answer:

40.5 N
