Kinematics Question 84
Question: Assertion : A positive acceleration of a body can be associated with a ’lowing down? of the body. Reason : acceleration is a vector quantity.
Options:
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.

Show Answer
Answer:
Correct Answer: B
Solution:
A body having positive acceleration can be associated with slowing down, as time rate of change of velocity decreases, but velocity increases with time, from graphis clear that slope with time axis decreases, but velocity increases with time.
