A ball is thrown upwards with a speed of `40m//s`. When the speed becomes half of the initial speed, gravity is switched off for next 2 second. After that gravity is again switched on but magnitude gravity is doubled. The  total distance travelled by the ball from `t=0` to the time when the ball reaches the maximum heighth is `55beta`. Find the value of `beta`.
