5n to the left and 20 n to the right. if the couch has a mass of 45 kg determine its acceleration
a) 3m/s2 to the right
b) 1.8 m/s2 to the right
c) 2.2 m/s to the right
d) 0.33 m/s2 to the right

D) 0.33 m/s² to the right

Explanation:

Apply Newton's second law.  Take right to be positive and left to be negative.

∑F = ma

20 N − 5 N = (45 kg) a

a = 0.33 m/s²

The couch accelerates at 0.33 m/s² to the right.

the answer is to check all of them! they all apply well at least i think so!
