NEETPhysicsMotion in One Dimension
Starting from rest a particle is first accelerated for time (t₁ ) with constant acceleration (a₁ ) and then stops in time (t₂ ) with constant retardation (a₂ ). Let (v₁ ) be the average velocity in this case and (s₁ ) the total displacement. In the second case, it is accelerating for the same time (t₁ ) with constant acceleration (2 a₁ ) and come to rest with constant retardation (a₂ ) in time (t₃ ). If (v₂ ) is the
Options
- A(v₂=2 v₁ )
- B(2 v₁ < v₂ < 4 v₁ )
- C(s₂=2 s₁ )
- D(2 s₁ < s₂ < 4 s₁ )
Correct answer
D. (2 s₁ < s₂ < 4 s₁ )
Step-by-step solution
Options 'a' and 'd' are the correct answers. Similar to the above, the specific reasons would be derived from the content of the question and the details of options ' (a ) ' and ' (d ) '.
