A particle moves along a circle of radius `(40)/(pi)` m with constant tangental acceleration. If the velocity of the particle is 100 m/s at the end of the 4th revolution after motion has begin, the tangential acceleration is

Options

A. `(125)/(8)`
B. `(35)/(6)`
C. `(26)/(3)`
D. `(5)/(4)`

Explanation

To find the tangential acceleration of a particle moving along a circular path, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Radius of the circle, \( r = \frac{40}{\pi} \) m
- Final velocity after 4 revolutions, \( v = 100 \) m/s
- Number of revolutions, \( n = 4 \)
