Question

a 5 kg box on a horizontal table is pushed by a horizontal force of 15N value of coefficient of friction=0.4. The value of normal force is

Answer 1

49 N

Step-by-step explanation:

The Normal Force (N) is the force of the table pushing up on the box, as a reaction to the force of the Weight (W) of the box pushing down on the table.

The two forces are equal

N = W = mg = (5 kg)(9.8 m/s²) = 49 N
