[SO00]

A 5.00-m-long ladder, weighing 200 N, rests against a smooth vertical wall with its base on a horizontal rough floor, a distance of 1.20 m away from the wall.
 
  The center of mass of the ladder is 2.50 m from its base, and the coefficient of static friction between the ladder and the floor is 0.200. How far up the ladder, measured along the ladder, can a 600-N person climb before the ladder begins to slip?
  A) 1.50 m
  B) 1.26 m
  C) 1.05 m
  D) 3.95 m
  E) 4.56 m

Question 2

A block is on a frictionless horizontal table, on earth. This block accelerates at 3.6 m/s2 when a 90 N horizontal force is applied to it. The block and table are then set up on the moon where the acceleration due to gravity is 1.62 m/s2.
 
  A horizontal force of 45 N is applied to the block when it is on the moon. What acceleration does this force impart to the block? A) 1.8 m/s2
  B) 1.6 m/s2
  C) 2.0 m/s2
  D) 2.2 m/s2
  E) 2.3 m/s2
