how much force is needed to accelerate an object of mass 90 kg at a rate of 1.2 m/s²?\n0.013 n\n75 n\n108 n\n1080 n
Answer
Explanation:
Step1: Recall Newton's second - law formula
$F = ma$ (where $F$ is force, $m$ is mass, and $a$ is acceleration)
Step2: Substitute given values
Given $m = 90$ kg and $a=1.2$ m/s², then $F=90\times1.2$ $F = 108$ N
Answer:
108 N (corresponding to the third option)
