Two blocks, having the same mass but different sizes, slide with the same constant speed on a smooth surface, then move onto a surface having friction coefficient k.
   
 
   
 
   Which stops in the shorter time?

  1. M1
  2. M2
  3. Both stop in the same time
  4. Cannot be determined

Question 2

A mass of 5 kg sits at rest on an incline making an angle of 30 to the horizontal. If s = 0.7, what is the friction force on the block?
 
  1.43.3 N, down the incline
  2.25 N, up the incline
  3.10 N, down the incline
  4.30.3 N, up the incline
  5.None of the above
