TS EAMCET · Physics · Motion In One Dimension
A body is thrown vertically upwards with a velocity of 35 \(\mathrm{ms}^{-1}\) from the ground. The ratio of the speeds of the body at times 3 s and 4 s of its motion is (Acceleration due to gravity \(=10 \mathrm{~ms}^{-2}\) )
- A \(3: 4\)
- B \(1: 1\)
- C \(2: 1\)
- D \(3: 2\)
Answer & Solution
Correct Answer
(B) \(1: 1\)
Step-by-step Solution
Detailed explanation
\(\begin{aligned} \mathrm{u} & =35 \mathrm{~ms}^{-1} \\ \therefore \quad \mathrm{t}_1 & =\mathrm{t}_2=\frac{\mathrm{u}}{\mathrm{g}}=\frac{35}{10}=3.5 \mathrm{~s}\end{aligned}\) \(\therefore\) The particle at time 3s and 4 s is at same level.…
