A plane has a speed of 650 km/hr. The wind is at a 90 degree angle to the plane with a speed of 75 km/hr. What are the magnitude and direction of the combined speed?
Show all work and include proper units.

Let the plane be flying east (to the right) and the wind north

Vx = 650 km/hr i                 speed to East

Vy = 75 km/hr j                    speed to North

V = (650^2 + 75^2)^1/2 = 654 km/hr       net speed

tan θ = Vy / Vx = 75 / 650 = .115        θ = 6.58 deg N of E

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
