A car P is moving with a uniform speed `5sqrt(3) m//s` towards a carriage of mass 9 kg at rest kept on the rails at a point B as shown in the figure. The height AC is 120 m. Cannon balls of 1 kg are fired from the car with an initial velocity 100 m/s with respect to the car at an angle `30^@` with the horizontal.

The first cannon ball hits the stationary carriage after a time `t_0` and sticks to it. Determine `t_0`. (in sec)
