E. VI.111 III/S9. An object of mass 4 kg is sliding down a friction lessinclined plane that makes an angle of 40 deg with thehorizontal. Calculate the component of gravitationalforce that pushes the object against the plane in adirection perpendicular to the inclined plane. (1 point)A. O 25.197 NB. 07.507 NC. 30.029 ND. 06.299 NE. 039.2 N

Respuesta :

In an inclided plane the perpendicular component of the weight to the plane is always given by:

[tex]W\cos\theta[/tex]

Plugging the values given in the problem we have:

[tex](4)(9.8)\cos40=30.029[/tex]

Therefore, the perpendicular component of the weight is 30.029 N
