If cabin is decending vertically with acceleration a and action by mass M on floor of cabin is 9Mg/10 then a equals to:
Show that the acceleration of any object down an incline where friction behaves simply (that g(sin @ — иk сos @). is, where fk = HK N) is a = g(sin 0 – µk cos 0). Note that the acceleration is independent of %3D mass and reduces when friction becomes negligibly small (Hk = 0). YA a

Part of Newton's 2nd Law says the acceleration of an object is inversely proportional to the mass of the object. So, if you were pushing a bucket along the floor, and someone dropped a rock (that has the same mass as the bucket) into the bucket, it's acceleration would O be doubled (increased by factor of 2) O be halved (decreased by a factor of 2) O wouldn't change O be quadrupled (increased by a factor of 4)
