1. In beta decay, an atomic nucleus emits an electron as it turns into another type of nucleus. A 2¹⁰Bi nucleus at rest decays to 210Po. Suppose the emitted electron moves to the right with momentum 5.60 x 10-22 kg m/s. The 210Po nucleus, with mass 3.50 x 10-25 kg, recoils to the left at a speed of 1.14 x 10³ m/s. Momentum conservation requires that a second particle, called an antineutrino, must also be emitted. Calculate the magnitude and direction of the antineutrino's momentum. 210PO 210Bi Before After e ?
A puck of mass mA that is moving along the +x axis with speed va collides with another puck of mass mB = 2mA. The collision is not head-on, so that after they collide, mB is located at 45◦ south of east, while mA collides head-on elastically with a stationary puck of mass mC = 3mA. If, after the second collision, the final velocity of mC is 0.450 [m/s], 25◦ north of east, what is the initial speed va?
