    Minimum velocity required by grasshopper

    There is no need of the distance from the log.And the grasshopper will scrape twice through the log.And the angle by which it scrapes the first part is 45 degrees.

    Kinematics-Motion in one dimension

    Yes thank you , I got the solution.Here it is as follows: From the first equation we get $$t_1=\frac{2u_1-2u}{f-f_1}$$ Now substituting the value of L in the second equation we get the desired result..
