Graph between the square of velocity (v) of a particle and the distance (s) moved is shown in figure. The acceleration of the particle in kilometers per hour square is:

  • Option 1)

    2250

  • Option 2)

    3084

  • Option 3)

    -2250

  • Option 4)

    -3084

 

Answers (1)

As learnt in

3rd equation or Velocity –displacement equation -

V^{2}-u^{2}=2as

V\rightarrow Final Velocity

s\rightarrow Displacement

u\rightarrowInitial velocity

a\rightarrowacceleration

-

 

 We use V2 = u2 + 2as

V2 - u2 = 2as

After solving we get acceleration of particle -3084
