An object speed is 7.2 m/s and its momentum is 360 kg m/s what is mass of object

Determine the maximum r-value of the polar equation r =3+3 cos 0

Newtons view of arrangement of the universe

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.
