Answer:
Centripetal Force
Explanation:
The reaction to the earth's pull on the moon is the centripetal force
Answer:
x = (mg-f)/k
Explanation:
there are three forces acting on cylinder in a tube, (1) force due to spring = -kx (2) force due to friction = f (3) force due to gravity.
we want to calculate an instant when all three forces acting on mass cancel and there is 0 net force and cylinder momentiraly comes to stop.
let's write it in mathematics.
kx+f-mg=0 (kx is positive because it is upwards and that is how we have setup our coordinate axis in this problem).
solving for x gives.
x = (mg-f)/k.
