(02.07 mc)
if a box with a mass of 8.0 kg is sitting on a frictionless surface experiences an acceleration of 4.0 m/s2 to the right, what is the net force acting on the box?
a 2.0 n
b 12 n
c 32 n
d 45 n

Explanation:

Step1: Recall Newton's second law

$F = ma$

Step2: Substitute given values

$m = 8.0\ kg$, $a=4.0\ m/s^{2}$, so $F=(8.0\ kg)\times(4.0\ m/s^{2})$

Step3: Calculate the net - force

$F = 32\ N$

Answer:

C. 32 N
