2. Suppose a wall clock has a second hand that is 12 cm long. An equation relating d. the distance of the tip of the second hand from the 'hon'zontal' (a level line through the middle of the clock) with t, time in seconds, beginning when the second hand is pointing up at 12 o'clock would be: ($0) = 123in[%(t 15)]. (a) Suppose the clock is running MEI than usual. Which part of the equation above would be affected? Explain why. Provide an equation showing the clocks second hand moving at a faster speed. . (b) Suppose the second hand was lenger than 12 em. Which part of the equation above would be affected? Explain why. Provide an equation representing a clock with a longer second hand. a (c) To ensure that the wall clock is placed at a good viewing height it is recommended that the minimum distance from h i f h n h n h r n be m than 180 cm and that maximum distance from the tip of the second hand to the ground he mthan 200 cm. Provide the equation of a function representing d, the distance from the tip of the second hand to the ground and it, time in seconds. beginning when the eemng hand is W. Show your work and explain why your equation works
