Question

Statement I: A body can have acceleration even if its velocity is zero at a given instant .
Statement II: A body is momentarily at rest when it reverses its direction of velocity.
A. (a) both Assertion and Reason are true and the Reason is correct explanation of the Assertion .
B. (b )both Assertion and Reason are true but the Reason is not a correct explanation of the Assertion.
C. (C ) Assertion is true but the Reason is false.
D. (d) both Assertion and Reason are false.

Answer 1

Correct Answer - D
When body while going vertically upwards, reaches at the highest point, then it is momentarily at rest and it then reverses its direction . AT the highest jpoint of motion the velocity is zero but its acceleration is equal to acceleration due to graveity.
