Aspy runs from the front to the back of an aircraft carrier at a velocity of 3.5 m/s. if the aircraft carrier is moving forward at 18.0 m/s, how fast does the apy appear to be running when viewed by an observer on a nearby stationary submarine?

The speed of the spy with respect to a stationary observer is 21.5 m/s.

The given parameters;

Let the backward motion = negative direction

Let the forward motion = positive direction

The relative velocity of the spy with respect to a stationary observer is calculated as;

Thus, the speed of the spy with respect to a stationary observer is 21.5 m/s.
