A net force of 40 N south acts on an object with a mass of 20 kg. What is the
object's acceleration?
(Hint: Use the formula a = f/m

A. a = 4 m/s 2 north
B. a = 2 m/s2 south
C. a = 10 m/s2 south
D. a = 20 m/s 2 north

Respuesta :

Answer:

B. 2m/s² south

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  = [tex]\frac{f}{m}[/tex]  

          a = [tex]\frac{40}{20}[/tex]   = 2m/s²

The acceleration of the object is 2m/s² south
