Answer: 93.5 m/s
Explanation:
Velocity is the rate of change of displacement per unit time. It is measured in metres per second.
i.e velocity = Displacement / Time taken
In this case,
Displacement = 935 centimeters north west
(Convert centimeters to metres)
Recall that 100cm = 1m
935 cm = 935/100 = 9.35m
Time taken = 10.0 seconds.
So, velocity = Displacement / Time taken
Velocity = 9.35 metres x 10.0 seconds
Velocity = 93.5 m/s
Thus, the velocity of the submarine moving north west is 93.5 m/s
