Based on what you have just read, what are the advantages of storing music digitally compared to using an analog system? sample response: storing music digitally requires less storage room than analog records or tapes. digital music is easier to copy and the copies are the same as the original. the quality of the signal does not degrade over long periods of time.

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
