A plane is heading south with a velocity of 150 kilometers/hour. It experiences a tailwind with a velocity of 20 kilometers/hour. Find the resultant velocity of the plane

the speeds are in the same direction:

170km/hr

High School Physics

To find the resultant velocity of the plane, we need to consider the effects of both the plane's velocity and the tailwind velocity. Since the tailwind is in the same direction as the plane's motion (south), we can add the two velocities together.

Resultant Velocity = Plane's Velocity + Tailwind Velocity

Resultant Velocity = 150 km/h + 20 km/h

Resultant Velocity = 170 km/h

Therefore, the resultant velocity of the plane is 170 kilometers/hour.
