MHT CET · Physics · Motion In One Dimension
The acceleration (a) - time (T) graph for the body starting from rest is given below. The maximum speed of the body is
- A \(40 \mathrm{~m} / \mathrm{s}\)
- B \(80 \mathrm{~m} / \mathrm{s}\)
- C \(160 \mathrm{~m} / \mathrm{s}\)
- D \(200 \mathrm{~m} / \mathrm{s}\)
Answer & Solution
Correct Answer
(A) \(40 \mathrm{~m} / \mathrm{s}\)
Step-by-step Solution
Detailed explanation
\(v_{max} = \text{Area under a-t graph from } T=0 \text{ to } T=10 \, \mathrm{s}\) \(v_{max} = \frac{1}{2} \times 10 \, \mathrm{s} \times 8 \, \mathrm{m/s^2}\)
