Question

As an airplane is flying 20.0 degrees north of east at a speed of 750 km/h. How fast is it moving to the north

Answer 1

in this case velocity of airoplane will be 750*sin20'

Answer 2

Answer:

$v_y=71.25\ m/s$

Explanation:

Given that,

Speed of an airplane, v = 750 km/hr = 208.33 m/s

An airplane is flying 20.0 degrees north of east, $\theta=20^{\circ}$

To find,

Velocity in north direction.

Solution,

Let $v_y$ is the speed of the airplane to the north. The y component of any motion is given by :

$v_y=v\ sin\theta$

$v_y=208.33\ m/s\ sin(20)$

$v_y=71.25\ m/s$

So, the airplane is moving with a speed of 71.25 m/s to the north direction.
