Question

"Three horizontal forces, 4.0 N to the right, 12 N to

the left, and 10 N to the right, are acting on a 2 kg object. What
is the acceleration (in m/s²) of the object?
a. 1/2
b. 1
c. 2
d. 3"

Answer 1

Net force right = 10 N + 4.0 N = 14.0 N

Net force left = 12 N

Net force on object = 14 - 1`2 = 2 N

a = F / m = 2 N / 2 kg = 1 m/s^2

(b) gives the correct answer
