KVPY2013PhysicsMotion in One Dimension

The accompanying graph of position x versus time t represents the motion of a particle. If p and q are both positive constants, the expression that best describes the acceleration of the particle is

Options

  1. Aa =- p - qt
  2. Ba=-p+q t
  3. Ca = p + qt
  4. Da=p-q t

Correct answer

D. a=p-q t

Step-by-step solution

From graph V first increases then decreases Hence a is earliar positive then negative a=P-q t
