A 11-kg sled sliding freely on an icy surface experiences a 4-N frictional force exerted by the Ice and an air-resistive force
of 0.6 N.
What is the net force acting on the sled?

Respuesta :

Answer:

The net force is 4.6 [N]

Explanation:

If the sled moves freely and with constant speed at that time, it is because there is no acceleration, therefore applying newton's second law of motion we can say that the sum of the forces acting on the sled is equal to zero.

The force that counteracts friction and wind must be directed in the opposite direction to these two.

- 4 - 0.6 + F = 0

F = 4.6 [N]
