Question

what is the frictional force produced by the road of a force of 20 N is given to block of mass 2 kgbproduces an acceleration of 5 ms​

Answer 1

Answer:

Frictional force produced by the road = 10N

Explanation:

According to Newton's 2nd Law of motion,

Unbalanced forces = ma

Where m=mass of the body

And a=accelration

So here, unbalanced force is external force,F - frictional force,f = ma

20 - f = ma

20 - 2*10 = f

Therefore, f =10N
