A small ball of mass m is attached to the end of the string of length l=1 m whose other end is fixed. From its lowest position, the ball is given a kinetic energy ml/5. the net acceleration (in `m//s^(2)`) of the ball at the instant when the string makes an angle `theta ` of `37^(@)C` with the downwards vertical is___________
