Physics Motion in a Straight Line Non-Uniform Motion MCQ (Single Correct)

A particle moves with an initial velocity v 0 and retardation α α v, where v is its velocity at any time t.

A

The particle will cover a total distance v 0 / α α .

B

The particle will come to rest after a time 1/ α α .

C

The particle will continue to move for a very long time.

D

The velocity of the particle will become v 0 /2 after a time 1 la.

Text Solution

Verified by Experts

The correct answer is:

v

or

or x -0 =

or

or v = v 0 e - α α t

∴ ∴ v = 0 for t → → ∞ ∞ .
