Parallelogram Law of Vector Addition

Verified by Experts

STATEMENT-1: In the figure shown, the y-component of velocity of m is (u_(1) cos theta_(1)+u_(2)cos theta_(2)) when the string is being pulled with speed u_(1) and u_(2) as shown in the figure. STATEMENT-2: According to parallelogram law of vector addition the sum of two independent vectors is given by the diagonal of the parallelogram if the two vectors are represented by the adjacent sides of the parallelogram.
