TS EAMCET · Physics · Motion In One Dimension
A body travels in a straight line from point \(A\) to point \(B\) with an initial velocity zero and uniform acceleration, covering \(1 \mathrm{~m}\) during the first second and \(39 \mathrm{~m}\) during the last second. The distance between \(A\) and \(B\) in metre is
- A 50
- B 100
- C 390
- D 400
Answer & Solution
Correct Answer
(D) 400
Step-by-step Solution
Detailed explanation
Distance travelled in first \(1 \mathrm{~s}\), \( \begin{aligned} \qquad s_1=\mathrm{lm} & =\frac{1}{2} a t^2 \\ \Rightarrow \quad a=\text { acceleration } & =2 \mathrm{~ms}^{-2} \end{aligned} \) Velocity after \(\mathrm{l} s,=u+a t\),…
