A rock is dropped from the top of a 2000-foot building. After 1 second, the rock is traveling 32 feet per second. After 2 seconds, the rock is traveling 64 feet per second. Let y be the rate of descent and x be the number of seconds since the rock was dropped
a. Write a linear equation that relates time x to rate y [Hint Use the ordered pairs (1,32) and (2,64)]
b. Use this equation to determine the rate of travel of the rock 19 seconds after it was dropped.
a. The linear equation that relates time x to rate y isy
b. After 19 seconds, the rock travels at the rate of
