We write unit vector notation in this format: ___i + ___j.
In the unit vector notation where do we place the value we find on the y-axis (the vertical distance covered by the vector)?
in front of the i
in front of the j
the y value cannot be found

Astone is dropped from a cliff and falls 9.44 meters. what is the speed of the stone when it reaches the ground? a. 13.6 m/sec b. 1.39 m/sec c. 185 m/sec d. 9.80 m/sec

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.

Each line (unit) on the horizontal axis represents: 5 years 10 years 20 years all of the above
