v-t graph of an object of mass 1 kg is shown. Select the Wrong statement.
Options
- AWork done on the object in 30 s is zero
- BThe average acceleration of the object is zero
- CThe average velocity of the object is zero
- DThe average force on the object is zero
Correct answer
C. The average velocity of the object is zero
Step-by-step solution
Initial velocity = final velocity = 0. As area under v-t graph is displacement displacement ≠ 0 therefore average velocity is not zero
