🎉 Announcing Numerade's $26M Series A, led by IDG Capital!Read how Numerade will revolutionize STEM Learning California State Polytechnic University, Pomona ### Problem 52 Easy Difficulty # At one instant, the center of mass of a system of two particles is located on the$x$-axis at$x=2.0 \mathrm{m}$and has a velocity of$(5.0 \mathrm{m} / \mathrm{s})$) One of the particles is at the origin. The other particle has a mass of 0.10$\mathrm{kg}$and is at rest on the$x$-axis at$x=8.0 \mathrm{m}$. (a) What is the mass of the particle at the origin? (b) Calculate the total momentum of this system. (c) What is the velocity of the particle at the origin? ### Answer ## (a)$m_{1}=0.30 \mathrm{kg}$(b)$\overrightarrow{\mathrm{p}}_{\text {tot}}=2.0 \hat{\mathrm{i}} \quad \mathrm{kg} \cdot \mathrm{m} / \mathrm{s}$(c)$\overrightarrow{\mathrm{v}}_{1}=6.67 \hat{\mathrm{i}} \mathrm{m} / \mathrm{s}\$
