A car starts moving along a line
Two particles start moving from the same point along the same straight line. The first moves with constant velocity v and the second with constant acceleration a. During the time that elapses before the sound catches the first, the greatest distance between the particle is.

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 height is 55β. Find the value of β.

A car starts moving along a line, first with acceleration a = 5m/s^2 starting from rest then uniformly and finally decelerating at the same rate till it comes to rest. The total of motion is 25s. The average speed during the time is 20m/s. The particle moves uniformly for (2.5x) second. Find the value of x.
