Document Summary
Nb: mark values are given in brackets [ ] beside each problem. Write all your answers on the quiz paper. Elastic collisions, target m2 stationary: v1 = (m1 m2) (m1+m2) u1, v2 = 2m1 (m1+m2) u1. Lorentz transformation: x = (x vt), t = (t v c2 x). Mass of proton = 1. 67 10 27 kg. 1 light-year = distance traveled by light in one year. Identical forces act for the same length of time on two di erent masses. What is the momentum of this proton: [5] a 4. 0-kg mass and a 9. 0-kg mass are being held at rest against a compressed spring, with one mass on each end, on a frictionless surface. 4. 0-kg mass moves to the right with a speed of 2. 0 m/s. [5] one 20-year-old twin sister takes a space trip with a speed of 0. 80c for 30 years according to a clock on the spaceship.
