An airplane travels at 300 mph in the direction cap s 45 degrees cap e What is the component form of the velocity vector?

The direction S 45° E means 45° east of south, so the velocity has a positive east component and a negative north–south component. Since the angle is 45°, both component magnitudes are 300 cos 45° = 300(√2/2) = 150√2. Thus the component form is ⟨150√2, −150√2⟩, choice C.
