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

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
