Apassenger on a moving train walks at a speed of 1.40 m/s due north relative to the train. the train is traveling at 3.5 m/s due east relative to the ground. what are the magnitude and direction of the velocity of the passenger relative to the ground

v= 4.9 m/s in east direction ( or  v=4.9 m/s * i )

Explanation:

Since the passenger moves along the train ( in the north direction relative to the train) then if the train is traveling east relative to the ground , the passenger will also travel to the east relative to the ground .  

Then the magnitude of the velocity will be

v= 1.40 m/S + 3.5 m/s = 4.9 m/s

v= 4.9 m/s

and the direction will be east ( if the x axis represents east direction and y-axis the north direction , then the velocity vector will be  v=4.9 m/s * i )

i think if it were me i whould divide 300 dide 15

step-by-step explanation:

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
