Motion in A Straight Line question

2023 · 10 Apr · Shift 2 · Q39

JEE MainPhysicsMotion in A Straight LineMCQ+4 / −1
A person travels xxx distance with velocity v1v_{1}v1​ and then xxx distance with velocity v2v_{2}v2​ in the same direction. The average velocity of the person is v\mathrm{v}v, then the relation between v,v1v, v_{1}v,v1​ and v2v_{2}v2​ will be.
  1. A
    V=V1+V2\mathbf{V}=\mathbf{V}_{1}+\mathbf{V}_{2}V=V1​+V2​
  2. B
    V=v1+V22V=\frac{v_{1}+V_{2}}{2}V=2v1​+V2​​
  3. C
    1v=1v1+1v2\frac{1}{\mathrm{v}}=\frac{1}{\mathrm{v}_{1}}+\frac{1}{\mathrm{v}_{2}}v1​=v1​1​+v2​1​
  4. D
    2 V=1v1+1v2\frac{2}{\mathrm{~V}}=\frac{1}{\mathrm{v}_{1}}+\frac{1}{\mathrm{v}_{2}} V2​=v1​1​+v2​1​
