Answer:
B. 2m/s² south
Step-by-step explanation:
Given parameters:
Net force = 40N
Mass = 20kg
Unknown:
Acceleration of the object = ?
Solution:
To solve this problem, we use;
F = ma
F is the net force
m is the mass
a is the acceleration
a =
a =
= 2m/s²
The acceleration of the object is 2m/s² south
