Question

3. A 5 meter, 200 N long ladder rests against a
wall. The ladder's center of mass is 3m from the
bottom. There is no friction on the wall, but there
is a coefficient of friction along the ground of
0.3. How far along the ladder can a 750 N
person climb above the ground.
hon anonymous question o) (4 Points)

Answer 1

Explanation:

For moving the body, applied force should be greater or equal to limiting friction tie, N). The limiting friction is

(a) Since, applied force F = 5 N, so body starts to move in forward direction.

(b) Here, applied force is lesser than limiting friction. So, body does not move.

( c) The reason is same as (b)
