A particle moves in straight line in same direction for 20 seconds with velocity 3m/s and the moves with velocity 4m/s for another 20 sec and finally moves with velocity 5m/s for next 20 seconds. What is the average velocity of the particle?

A particle is projected with a velocity v so that its range on a horizontal plane is twice the greatest height attained. If g is acceleration due to gravity then its range is:
