A jet airliner moving initially at 693 mph (with respect to the ground) to the east moves into a region where the wind is blowing at 798 mph in a direction 37◦ north of east. What is the new speed of the aircraft with respect to the ground? Answer in units of mph.

The new speed of the aircraft with respect to the ground is 1414.3 mph.

Explanation:

Given that,

Angle = 37°

Velocity of jet airliner = 693 mph

Velocity of wind = 798 mph

We know that,

The new velocity of the aircraft with respect to the ground

We need to calculate the new speed of the aircraft with respect to the ground

Using formula for velocity

Put the value into the formula

Hence, The new speed of the aircraft with respect to the ground is 1414.3 mph.
