Two cars A and B are moving with velocities 20 m/s and 15 m/s in the direction east and west respectively. If they started from the same place at the same time, what would be the distance between them after 2 min? Find

the distance covered by each car at the same time. (2 min).​

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.
