question 22 of 25
what force is required to give an object with mass 50 kg an acceleration of 8 m/s²?
a. 400 n
b. 58 n
c. 6.25 n
d. 250 n

Explanation:

Step1: Recall Newton's second - law formula

$F = ma$

Step2: Substitute given values

$m = 50$ kg, $a=8$ m/s², so $F=50\times8$

Step3: Calculate the force

$F = 400$ N

Answer:

A. 400 N
