-27 An unstable particle with a mass equal to 3.34 × 107 kg is initially at rest. The particle decays into two fragments that fly off with velocities of 0.988c and -0.859c, respectively. Find the masses of the fragments. (Hint: Conserve both mass-energy and momentum.) m (0.988c) kg kg m(-0.859c) =
In 1977 the planet Alderaan, with a mass of 3 x 1024 kg, exploded. Assuming it was initially at rest and experienced no external interactions, 3. A) If the planet blew apart into two pieces with 40% of its mass flying away in one piece at 4,000 km/s, what speed did the rest of the planet have relative to its original frame? B) If the planet blew apart into three pieces, with 30% of its mass flying away at 3,000 km/s, and 20% of its mass flying away at 5,000 km/s at an angle of 120° relative to the velocity direction of the first fragment, what velocity did the rest of the planet have? Report the direction by specifying its angle relative to the velocity direction of the first fragment.
B8] This question concerns two inertial frames S and S' with origins coinciding at t = t' = 0, and a set of events taking place along the x-axis, which defines the direction of relative motion. -8 a) The coordinates of event A in frame S are x = 12 m and t = 8x10 s. If the coordinates of this event in frame S' are x' = -3 m and t' = 7 x 10- s, show that the y factor for transformations between S and S' is 5/4. b) Events B and C take place in S' at a time t' = 6 × 10-* s at x' = 1 m and x' = 2 m respectively. What is their spatial separation in frame S? %3D -8- c) Event D takes place in S' at t' = 3 x 10 s and x' = 1 m. What is the time difference between events B and D in S? d) Is it possible for events A and D to take place at the same time in the frame of an observer moving along the x-axis?
An electron-positron collider creates muons through the reaction et +e →µ* +µ. In the center-of-momentum frame, what is the minimum speed of the electron for this reaction to occur, in terms of the masses me and mu of the electron and muon? Oc(1-) 2m 7ne - my O This process can occur at any speed.
