A particle of mass 1 kg is subjected to a force which depends on the position as with k = 1 kg s -2 . At time t = 0, the particle's position and its velocity , Let v x and v y denote the x and the y components of the particle's velocity, respectively. Ignore gravity. When z = 0.5 m, the value of (x v y - y v x ) is_____m 2 s -1 .
