Question

an aeroplane flies with a velocity of 100km/h at an angle of 60 to the horizontal. Calculate its effective velocity in the notherly direction and easterly direction

Answer 1

Step-by-step explanation:

to find the velocity across the positive y direction we multiply 100 by sin60.

to find the velocity across the positive x direction we multiply 100 by cos60.

horizontal: 50 km/h

vertical: 86.6 km/h
