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

Options

  1. Aa=−p−qt\mathrm{a}=-\mathrm{p}-\mathrm{qt}
  2. Ba=−p+qta=-p+q t
  3. Ca=p+qt\mathrm{a}=\mathrm{p}+\mathrm{qt}
  4. Da=p−qta=p-q t

Correct answer

D. a=p−qta=p-q t

Step-by-step solution

From graph V\mathrm{V} first increases then decreases Hence a\mathrm{a} is earliar positive then negative a=P−qt\mathrm{a=P-q t}
