Work, Energy and Power & Circular Motion

A particle (m = 1 kg) slides down a frictionless track (AOC) starting from rest at a point A (height 2 m). After reaching C, the particle continues to move freely in air as a projectile. When it reaching its highest point P (height 1 m), the kinetic energy of the particle (in )) is : (Figure drawn is schematic and not to scale; take g = 10 ms -2 )
