Question

What is the acceleration of this object? The object's mass is 2 kg.

Answer 1

4 m/s2

i took the test and got the correct answer from it

Answer 2

The resultant force from the diagram is 8N towards east.

We Know, F = m*a
Here, F = 8 N
m = 2 Kg

Substitute their values in expression,
8 = 2*a
a = 8/2
a = 4

So, your final answer & acceleration of the object would be 4 m/s² towards East.

Hope this helps!
