Question
A body of mass 2 kg slides down a curved track which is quadrant of a circle of radius 1 metre. All the surfaces are frictionless. If the body starts from rest, its speed at the bottom of the track is
- 4.43 m/sec
- 2 m/sec
- 0.5 m/sec
- 19.6 m/sec
The correct answer is: 4.43 m/sec
By conservation of energy,
