Express the result of the following calculation, in scientific notation, to the proper number of significant figures: ((395600.1)/(6.72)) + 19.
 
  What will be an ideal response?

Question 2

Imagine hitting a heavy anvil with a hammer. The hammer is in contact with the metal for a short period of time. How do you suppose the time of contact depends upon how hard you hit the anvil (i.e.
 
  , does a hard hit remain in contact much longer or shorter than a light tap?) It is reasonable to assume Hooke's law of elasticity to hold.

Answer to Question 1

5.9  104

Answer to Question 2

The anvil has an effective elastic constant which is relatively large. The time of contact does NOT depend upon the strength of the blow. The PERIOD of oscillation (the time in contact is half a period) is independent of the amplitude for SHM.
