Question

A particle moves with velocity 10m/s along x-axis 5m/s along y-axis and 15m/s along z-axis find velocity vector

Answer 1

Answer:

5√14 m/s

Step by step explanation:

Hii mate,

Resultant vector of 3 vectors in x,y,z axis,

V=√[(Vx)²+(Vy)²+(Vz)²]

Here, in this question,

Given,

Velocity along x-axis , Vx = 10 m/s

Velocity along y-axis , Vy = 5 m/s

Velocity along z-axis , Vz = 15 m/s

So, Resultant Velocity Vector,

V=√[(Vx)²+(Vy)²+(Vz)²]

  = √(10²+5²+15²)

  = √(100+25+225)

  = √350

  = √(2×5×5×7)

  = 5√(2×7)

  = 5√14 m/s

Hence,

Resultant Velocity Vector = 5√14 m/s
