An astronaut is standing on the surface of a planetary satellite that has a radius of 1.74  106 m and a mass of 7.35  1022 kg.
 
  An experiment is planned where a projectile needs to be launched straight up from the surface. What must be the minimum initial speed of the projectile so it will reach a height of 2.55  106 m above this satellite's surface? (G = 6.67  10-11 N  m2/kg2)

Question 2

If an electron is accelerated from rest through a potential difference of 9.9 kV, what is its resulting speed? (e = 1.60  10-19 C, k = 1/40 = 8.99  109 N  m2/C2, mel = 9.11 x 10-31 kg)
 
  A) 3.9  107 m/s B) 5.9  107 m/s C) 2.9  107 m/s D) 4.9  107 m/s

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).
