Question

What is the magnitude, in newtons, of the frictional force acting on the block?

a) "40 N"
b) "20 N"
c) "10 N"
d) "5 N"

Answer 1

The magnitude of the frictional force acting on the block is 8 N.

Step-by-step explanation:

The magnitude of the frictional force acting on the block can be found using the formula:

frictional force = coefficient of friction * normal force

In this case, the coefficient of friction is 0.20 (given) and the normal force is equal to the gravitational force, which is 40 N (given).

Therefore, the frictional force is:

frictional force = 0.20 * 40 N = 8 N

So, the magnitude of the frictional force acting on the block is 8 N.
