Question

the velocity components of an object along x ans y axis are Vx=20m/s and Vy=40m/s respectively.Its direction of velocity thita = ___​

Answer 1

Explanation:

V=20/x ,V=40/y

20/x = 40/y

20 y=40x

xy =20

So , V1=1 ,V2 =2

Answer 2

The velocity angle θ will be 63.435° from the ground.

Step-by-step Explanation:

Given: Vx = 20 m/s and Vy = 40 m/s

To Find: The velocity angle θ

Solution:

• Finding the velocity angle θ

We know that the velocity components of the object are,

Vx = Vcosθ = 20 m/s . . . . . . . (1)

Vy = Vsinθ = 40 m/s . . . . . . . (2)

Dividing (2) by (1), we get

tanθ = 2

⇒ θ = tan⁻¹ (2) = 63.435°

Hence, the velocity angle θ will be 63.435° from the ground.
