Frames S and S' are moving relative to each other along the x and x' axes. They set their clocks to t = t' = 0 when their origins coincide. In frame S, event 1 occurs atx1 = 4 c · y and t1 = 1 y and event 2 occurs at x2 = 8.0 c · y and t2 = 0.5 y. These events occur simultaneously in frame S'.
(a) Find the magnitude and direction of the velocity of S' relative to S.
(b) At what time do both of these events occur as measured in S'?
(c) Compute the spacetime interval ?s between the events.
(d) Is the interval spacelike, timelike, or lightlike?
(e) What is the proper distance Lp between the events?
An airplane is flying through a thundercloud at a height of 2400 m. (Flying at this height is very dangerous because of updrafts, turbulence, and the possibility of electric discharge.)
A piece of unpainted wood barely floats in a container partly filled with water. If container is sealed and then pressurized above atmospheric pressure, does the wood rise, sink, or remain at the similar level.
An 79-kg stuntman jumps from a window of a building situated 33 m above a catching net. Assuming that air resistance exerts a 100-N force on the stuntman as he falls, identify his velocity just before he hits the net.
A car is travelling at a constant speed of 31.1 m/s on a highway. At the instant this car passes an entrance ramp, a second car enters the highway from the ramp. The second car starts from rest and has a constant acceleration. What acceleration mu..
