Always use significant figure rules. remember that these rules apply to all numbers that are measurements.
a caterpillar tries to climb straight up a wall two meters high, but for every 2 cm up it climbs, it slides down 1 cm. eventually, it reaches the top. when it reaches the top, it does not pull itself over so it will slide down 1 cm. at this point, the caterpillar was exhausted and fell to the ground. what is the total displacement?
