The figure below shows a toy car moving in a circular rail in a vertical plane. The mass of the toy car is 300g and the radius of the rail is 2m.

Q1422820191136.png


Determine:
i) Minimum velocity at which the toy passes point A


ii) If the toy was tied by a string at the centre of the rail path, following the same circular path, when whirled at which position (A or B) would the string experience maximum tension. Explain your answer.


iii) If the toy moves with a velocity of 5m/s as it passes point B, find the angular velocity at this point.

iv) State two applications of uniform circular motion
