Multiple Choice

If a person is about to push with +400N a mass of 40kg. Is it going to be moved? (µs=0.6, µd=0.4, g≈10)

1

Yes, and while it's moving Ffd = -160N.

2

Yes, and while it's moving Ffd = -240N.

3

No, because its Ffs max = 240N

4

No, because its Ffs max = 160N

Multiple Choice

If a person is about to push with +400N a mass of 90kg. Is it going to be moved? (µs=0.6, µd=0.4, g≈10)

1

Yes, and while it's moving Ffd = -540N.

2

Yes, and while it's moving Ffd = -360N.

3

No, because its Ffs max = 540N

4

No, because its Ffs max = 360N
