You are trying to escape the potential impact area and head 500km south and then 400 km west. You see on the news that you haven't gone far enough away from the impact zone, so you head another 200 km south and 300 km west. Calculate your distance traveled.
Calculate your displacement.
If the trip took 11.5 hours, what was your average speed in kilometers per hour?

Asimply means that over time there was some sort of change.

An airplane flies eastward and always accelerates at a constant rate. at one position along its path it has a velocity of 34.3 m/s, it then flies a further distance of 40100 m and afterwards its velocity is 47.5 m/s. find the airplane\'s acceleration and calculate how much time elapses while the airplane covers those 40100 m.

Which of the following correctly describes what happens when an atomic bomb explodes? small pieces of fissionable material are joined and form a body with a mass greater than the critical mass, the relative number of neutrons escaping decreases, and a chain reaction and explosion result. large pieces of fissionable matter are brought together quickly and form a body with a mass smaller than the critical mass, the relative number of escaping neutrons increases, and a chain reaction and explosion result.
