11. A pebble falls from the top of a cliff that is 180 m high. The pebble's height above the ground is modeled by h(t)=−5t2−5t+180, where h is the height in metres at t seconds since the pebble started to fall. a) Find the rate of change of height in the first 5 seconds. 3) b) What does this rate of change indicate?
