MHT CET · Physics · Motion In One Dimension
A moving body is covering distances which are proportional to square of the time. Then the acceleration of the body is
- A decreasing.
- B Constant but not Zero
- C Zero
- D Increasing
Answer & Solution
Correct Answer
(B) Constant but not Zero
Step-by-step Solution
Detailed explanation
\(s \propto t^{2}\)
\(s=k t^{2}\)
\(\frac{d s}{d t}=2 k t\)
\(\frac{d^{2} s}{d t^{2}}=2 k\)
\(s=k t^{2}\)
\(\frac{d s}{d t}=2 k t\)
\(\frac{d^{2} s}{d t^{2}}=2 k\)
