A particle starts from rest with constant acceleration. The ratio of space-average velocity to the time-average velocity is:
where time-average velocity and space-average velocity, respectively, are defined as follows:
\(<v>_{time}\) \(=\) \(\frac{\int v d t}{\int d t}\)
\(<v>_{space}\) \(=\) \(\frac{\int v d s}{\int d s}\)
1. | \(\frac{1}{2}\) | 2. | \(\frac{3}{4}\) |
3. | \(\frac{4}{3}\) | 4. | \(\frac{3}{2}\) |
