A cannon fires a shell at the angle of 45° above the horizontal. The shell consists of a mass of 15.7 kg, and its initial speed as it leaves the cannon is around 298 m/s. The cannon are not anchored to the ground. It is on wheels and sitting on the level roadway. When the road applies a steady friction force of 340 N on the cannon’s rolling wheels, determine how much time does it take for the cannon to stop rolling after it fires the shell?
