Assertion : If a particle is thrown upwards, then distance travelled in last second of upward journey is independent in last second of upward journey is independent of the velocity of projection.
Reason : In last second, distance travelled is `4.9m`. (Taken, `g=9.8 ms^(-2)`)

A

If both Assertion and Reason are correct and Reason is the correct explanation of assertion.

B

If both Assertion and Reason are correct but Reason in not the correct explanation of Assertion.

C

If Assertion is true but Reason is false.

D

If Assertion is false but Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
Last second of upwards journey is the first second os downward journey.
`therefore` Distance travelled `=(1)/(2)g t^(2)=(1)/(2)xx9.8xx(1)^(2)=4.9m`
