What momentum does a 70 kg person running 10m/s (a fast sprint) have ?

Porque crees que el agua no podia subir mas de 10 m de altura con ese tipo de bomba

The softest and hardest minerals are: softest hardest

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.
