A particle moves along a circle of radius \(\left(\frac{20}{\pi}\right)\) m with constant tangential acceleration. If the velocity of the particle is 80 m/s at the end of the second revolution after motion has begun, the tangential acceleration is:
- 160\(\pi\) m/s2
- 40 m/s2
- 40\(\pi\) m/s2
- 640\(\pi\) m/s2
Answer
(B) 40 m/s 2
