Physics - Center of Mass Question with Solution | TestHub

Two masses m and m, that start simultaneously from the inter-section of two straight lines with velocities $3\mathrm{m}/\mathrm{s}$ and $4\mathrm{m}/\mathrm{s}$ respectively on a horizontal surface as shown. Find the two times of magnitude of the velocity of centre of mass (in $\mathrm{m}/\mathrm{s}$ ) when $\theta =90^{\circ }$.
