a- We look at a cardboard box from above. The box weighs 28 N. It is on a smooth surface with which μS = 0.83 and μK = 0.65. Someone pushes it in the direction of the red arrow (0º) with a force F of 8 N. At that moment, the box is sliding towards 90º (it is sliding on the surface). Indicates the amount of force that friction is exerting on the box, in N. b-The direction of the friction force in the above case is towards... (answer in degrees)
