The period P of oscillation of a pendulum (the time interval needed to complete one full oscillation) can be expressed in terms of the mass m of the plumb bob, the length l of the string, and the acceleration due to gravity, g, as P = kmb1cgd, where
 
  k, b, c, and d are dimensionless constants. What must be the values of b, c, and d?

Question 2

The position of an object as a function of time is given by x(t) = at3  bt2 + ct - d, where a = 3.6 m/s3, b = 4.0 m/s2, c = 60 m/s, and d = 7.0 m.
 
  (a) Find the instantaneous acceleration at t =2.4 s.
  (b) Find the average acceleration over the first 2.4 seconds.

Did you know?

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).
