Three objects move on a horizontal surface of friction μ = 0.2. If F=24 N, what is the force (in N)
exerted on the 2.0 kg object by the 3.0 kg object?

Three objects move on a horizontal surface of friction μ 02 If F24 N what is the force in N exerted on the 20 kg object by the 30 kg object class=

Respuesta :

The net force exerted on the 2.0 kg object by the 3.0 kg object is 14 N.

What is the net force acting at the end of the 3.0 kg object?

The net force acting on the 3.0 kg object is determined as follows:

  • Net  force = applied force - frictional force

Frictional force on acting on the 1.0 kg object = 0.2 * 1.0 * 10 = 2 N

Net force = 24 - 2 = 22 N

Net force acting at the end of the 2 kg object is determined as follows:

Net  force = applied force - frictional force

Frictional force on acting on the 1.0 kg and 3.0 kg object = 0.2 * 4.0 * 10 = 8 N

Net force = 22 - 8  = 14 N

Therefore, the net force exerted on the 2.0 kg object by the 3.0 kg object is 14 N.
