A train, travelling with velocity v = 0.8c, enters a tunnel. The train has proper length 100m and the tunnel has proper length 80m. When the center of the train coincides with the center of the tunnel, two gates located at either end of the tunnel come crashing down. The three events (the center of the train reaching the center of the tunnel, the front gate closing and the rear gate closing) occur simultaneously in the stationary reference frame. a) Describe the order of the events in the train’s reference frame. b) Where are the two ends of the train (from the point of view of each reference frame) when each of the events occurs?

A train with proper length L moves at speed 4c/5 with respect to the ground. A ball is thrown from the back to the front, at speed c/3 with respect to the train. How much time does this take, and what distance does the ball cover, in: (a) The train frame? (b) The ground frame? Solve this by i. Using a velocity-addition argument, as we did in lecture. ii. Using the Lorentz transformations to go from the train frame to...

A snake of proper length 100 cm is moving at speed v = 0.6c to the right across the table. A mischievous boy, wishing to tease the snake, holds two hatchets 100 cm apart and plans to bounce them simultaneously on the table so that the left hatchet lands immediately behind the snake’s tail 1 . The boy argues as follows: “The snake is moving with v = 0.6c, therefore, its length measured in my frame is 100cm γ =...

An observer (O) is standing on a long tunnel that has a rest length of 12 c.µs. O sees a long train that he measures to be 12c.µstravel through the tunnel at a speed of 0.600c. The front and back of the tunnel are mounted with strobe lights so that when the front or end of the train reaches the end of the tunnel the light flashes. So we have 4 events (flashes). Event 1: Front of train enters tunnel. Event 2: Front of...

An electron with velocity v = 2.0x106 m/s directed along +y axis enters in a region of uniform electric field, E = 8.0 x 103 V/m directed along +y axis. What is the magnitude and direction of the acceleration of the electron? How long does it take for the electron to stop instantaneously? Answer: 15 2 a = 1.4x10 m/s , directed along – y-axis, t = 1.4 ns

A train, A, with a mass of 19,000 kg is travelling at 90 km/h when it strikes a second train, B, which has a mass of 17,000 kg and is moving in the same direction at a speed of 43.2 km/h. If the coefficient of restitution for the collision is 0.87 and all resistances to motion are negligible, then (i) calculate the speed of the trains A and B immediately after the impact.

If V is a linear space and S is a proper subset of V, and we define a relation on V via v1 ~ v2 iff v1 - v2 are in S, a subspace of V. We are given ~ is an equivalence relation, show that the set of equivalence classes, V/S, is a vector space as well, where the typical element of V/S is v + s, where v is any element of V.

A negative charge, -q, has a mass, m, and an initial velocity, v, but is infinitely far away from a fixed large positive charge of +Q and radius R such that if the negative charge continued at constant velocity it would miss the center of the fixec charge by a perpendicular amount b. But because of the Coulomb attraction between the two charges the incoming negative charge is deviated from its straight line course and attracted to the fixed charge...
