NEET 2003 Physics question
A particle moves along a circle of radius 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 : -
Answer: (1)
Solution
The motion starts from rest () and the tangential acceleration is constant, so the equation applies along the circular path. Distance covered in two revolutions: \frac{20}{π}$ =
