Acruise ship travels west at 25.0 m/s. john is taking his morning jog on the upper deck and jogs from the port side to the starboard side at 5 m/s. what 8s john velocity with respect to the water?

25 m/sec

Explanation:

If the water is assumed to have zero velocity with respect to the boat, John and travels perpendicular  to the boat traveling direction going from port to starboard, his velocity with respect to the water is the same as the ship, 25.m/sec

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048
