The velocity-time graph of a particle in one-dimensional motion is sho

1.	The velocity-time graph of a particle in one-dimensional motion is shown in Fig.Which of the following formulae are correct for describing the motion of the particle over the time-interval t1 to t2
Answer» 1. Wrong, because it is not known whether the acceleration ‘a’ is constant. 2. Wrong, because it is not known whether the acceleration ‘a’ is constant. 3. Correct. By definition. 4. Correct. By definition 5. Wrong. The formula should contain v₁ (t) instead of v_average. 6. Correct By definition.
