A particle starts from rest at A moves with uniform acceleration a m//

1.	A particle starts from rest at A moves with uniform acceleration a m//s^(2) in a straight line. After 1/a Seconds a second particle starts from A with initial velocity 'u' and moves same direction. If u gt 2m//s then during the entire motion the second particle remains ahead of first particle for the duration of k (sqrt(u(u-2)))/(a). The value of 'k' is
