Question

5kg object with two forces acting on it: 8N to the right and 3N to the left. calculate the acceleration of the object

Answer 1

Answer:

a = 1 m/s^2

Explanation:

if we assume that right is the positive x direction and y is the negative x-direction then we get:

Fr = 8N

Fl = -3N

We then find the net force acting upon the object

Ft = Fr + Fl

Ft = 8N - 3N

Ft = 5N

After we find net force acting upon the object we can then use Newton's 2nd Law to find its acceleration.

Ft = m*a

Isolate accerleration

a = Ft / m

a = 5N / 5kg

a = 1 m/s^2
