Question  no.2 page 49​ 2. Two intersecting straight lines move translationally in opposite directions with velocities VI and v2 perpendicular to the corresponding lines. The angle between the lines is u. Find the speed of the point of intersection of these lines.

Dear Student,
                       Divide the velocities in perpendicular axis let X-axis and Y-axisY-component will add up while X-component will subtractedthen velocity of intersecting point={v1cosα/2+v2cosα/2}2+{v1sinα/2-v2sinα/2}2=v12+v22+2v1v2cos(α)
Regards
