I need solve this questions

(25 points) A box of mass 70 kg rests on a wooden oor where p3 = 0.2 and pk =0.l. 1) (5 points) The magnitude of the normal force = N 2) (2 point) In the formula-sheet provided which equation can be used to calculate the maximum static friction 3) (5 points) The magnitude of the maximum static friction force = l: N The box starts to slide after a force F =177.2 N is applied. 4) (5 points) The magnitude of the kinetic friction force = N 5) (3 points) The magnitude of the net force: C] N 6) (5 points) The speed of the box after 7 seconds- - m/s
