The graph shows the variation of 1 ~V (where V is the velocity of the particle) with respect to time. Then find the value of acceleration at t =3 sec .

Options

  1. A3 ~m / s ^2
  2. B5 ~m / s ^2
  3. C1 ~m / s ^2
  4. DNone of these

Correct answer

A. 3 ~m / s ^2

Step-by-step solution

At t=3 Slope = d ( 1 V ) d t =-1 - 1 ~V ^2 dV dt =-1 ( 1 3 )^2 dV dt =1 a = dV dt =3 ~m / s ^2
