Catalyst: 2/5/18 ~On her fishing trip Lauren takes the boat 12 km south. She falls asleep and the boat drifts 4 km west. What was her displacement? ~It takes Emily 0.25 hours to drive to school. Her route is 16 km long. What is Emily’s Average Speed on his drive to school? ~A little kitten startles Blake.The sweet little kitten accelerates from 2 m/s to 10m/s in 4 seconds. Because Blake is so scared, he runs away as fast as he can from 0 m/s to 5m/s in 2 seconds. Who is accelerating faster, the kitten or Blake?
