TS EAMCET · Physics · Motion In One Dimension
An object moves in a straight line with deceleration whose magnitude varies with velocity as \(3 v^{2 / 3}\). If at an initial point, the velocity is \(8 \mathrm{~m} / \mathrm{s}\), then the distance travelled by the object before it stops is
- A \(2 \mathrm{~m}\)
- B \(4 \mathrm{~m}\)
- C \(6 \mathrm{~m}\)
- D \(8 \mathrm{~m}\)
Answer & Solution
Correct Answer
(B) \(4 \mathrm{~m}\)
Step-by-step Solution
Detailed explanation
Given that, \(a=\) deceleration \(=-3 v^{2 / 3} \mathrm{~m} / \mathrm{s}^2\) At initial point \((t=0)\) velocity \(=8 \mathrm{~m} / \mathrm{s}\) Distance travelled by the object before it stop is We know that,…
