Question

A triangular wedge of mass m is placed on smooth surface as shown in figure. A person having mass equal to that
of wedge starts running over it with a constant acceleration 3 m/s2 upwards, relative to the wedge along AB and
runs down with acceleration 16/13 m/s along BC, relative to the wedge. The initial coordinates of the point 'A' are
taken as (0, ). Initial speed along the path BC is same as that of the final speed attained along path AB, relative to
the wedge. (Assume sufficient friction between man and wedge so that there is no slipping between them). If the
x-coordinates is a then ta of man when he reaches the end of the wedge.
