AP EAMCET · PHYSICS · Motion In One Dimension
A body starting from rest moving with an acceleration of \(\frac{5}{4} \mathrm{~ms}^{-2}\). The distance travelled by the body in the third second is:
- A \(\frac{15}{8} m\)
- B \(\frac{25}{8} m\)
- C \(\frac{25}{4} m\)
- D \(\frac{12}{7} m\)
Answer & Solution
Correct Answer
(B) \(\frac{25}{8} m\)
Step-by-step Solution
Detailed explanation
\(\mathrm{u}=0, \mathrm{a}=\frac{5}{4} \mathrm{~ms}^{-2}\) \(S_{n t h}=u+(2 n-1) \frac{a}{2}\) \(\therefore \quad \mathrm{S}_{3 \mathrm{rd}}=0+(2 \times 3-1) \times \frac{5}{8}=\frac{25}{8} \mathrm{~m}\)
