A car and a jeep are 7km apart. The car starts from rest and travels towards the jeep
with an acceleration of 3.5 m/s^2. The jeep starts from rest and travels towards the car
with an acceleration of 2.25 m/s^2. Where will they meet if they started at the same time?
~~~~~~~~~~~~~~~~ 

Write the total distance equation as the sum of two partial distances for uniformly accelerated moves 
from each end

    %283.5%2At%5E2%29%2F2 + %282.25%2At%5E2%29%2F2 = 7000  meters.


It gives

    5.75%2At%5E2 = 14000

    t%5E2 = 14000%2F5.75 = 2434.783

    t = sqrt%282434.783%29 = 49.34 seconds.    ANSWER

Solved.
