Question

3. An aeroplane takes off at an angle of 60° to the
horizontal. if the velocity of the plane is
200km/h, calculate its horizontal and vertical
component of its velocity?​

Answer 1

Answer:

200cos60 & 200sin60 respectively.

Answer 2

Horizontal component

vx=v cos 60°

=200×1/2

=100 km/hr

vertical component

vy=sin 60°

=200×✓3/2

=100 ✓3 km/hr

we can have two mutually perpendicular components of a vector other than x-direction or y-direction.
