The acceleration vs distance graph for a particle moving with initial velocity 5 ~m / s is shown in the fiture. The velocity of the particle at x=35 ~m will be

Options

  1. A20.62 ~m / s
  2. B20 ~m / s
  3. C25 ~m / s
  4. D50 ~m / s

Correct answer

C. 25 ~m / s

Step-by-step solution

Area of graph array l = adx = vdv dx d x == _ V _ i ^ v _ f v d v = [ v ² 2 ]_ v _ i ^ v _ f , 150+150= 1 2 [ ~V _ f ²- V _ i ² ] array array l 300 2=V_ f ²-(5)² V_ f ²=600+25, V_ f =25 array
