To this end, so-called grey hydrogen is widely used today, which is obtained from oil and natural gas, while efforts are made to replace it with green hydrogen, which comes from renewable sources. W, A ball with mass m=1 \ kg and speed v_o=5 \ m/sec elastically collides with a stationary, identical ball (all resting on a frictionless surface so gravity is irrelevant). B. r 3. stream And we can plug this result into our energy conservation equation, and see what simplifying this equation algebraically reveals: {eq}(0.22 + m_2)(\frac{m_2 v_f}{0.22 - m_2})^2 = m_2 v_f^2\\ Two titanium spheres approach each other head-on with the same speed and collide elastically.
