AP EAMCET · PHYSICS · Motion In One Dimension
A body of mass 1.5 kg is moving towards south with a uniform velocity of \(8 \mathrm{~ms}^{-1}\). A force of 6 N is applied to the body towards east. The displacement of the body 3 seconds after the application of the force is
- A 24 m
- B 30 m
- C 18 m
- D 42 m
Answer & Solution
Correct Answer
(B) 30 m
Step-by-step Solution
Detailed explanation
\begin{aligned} & \mathrm{m}=1.5 \mathrm{~kg}, \mathrm{~F}=6 \mathrm{~N} \\ & \overrightarrow{\mathrm{v}}=-8 \hat{\mathrm{j}}, \mathrm{t}=3 \mathrm{~s} \\ & \overrightarrow{\mathrm{a}}=\left(\frac{\mathrm{f}}{\mathrm{~m}}\right) \hat{\mathrm{i}}=\left(\frac{6}{1.5}\right)…
