Ok so this question is trying to troll me. 10 pts
study the graph shown. it is a graphic of a car trip taken by karen and her mother. the starting position (0,0) is their home.
identify the time period(s) during the trip when the car was stopped.
a) first and third hour
b) second and fifth hour
c) third and fourth hour
d) first and fifth hour

Could someone me find the answer to this problem.

Two cannon balls weighing 18 kg and 24 kg are chained together and fired horizontally with a velocity of 165 m/s from the top of a 21-m wall. the chain breaks during the flight of the cannonballs and the 18-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire. determine the position of the other cannonball at that instant. neglect the resistance of the air.

Which sections of the heating curve illustrate this process?
