An aeroplane takes off at an angle of `60^(@)` to the horizontal.If the velocity of the plane is `200kmh^(-1)`,calculate its horizontal and vertical component of its velocity.

Text Solution

Verified by Experts

Here `v=200 km h^(-1),theta=60^(@)`

`:.`Horizontal component
`v_(x)=vcos theta=200cos60^(@)`
`=200xx1/2=100Km h^(-1)`
Vertical component
`v_(y)=vsin theta=200sin60^(@)=200xxsqrt(3)/2=100 sqrt3Km h^(-1)`
