Two trains A and B each have proper length L and move in the same direction. A person C is on theground, and observes that train A is behind train B. Observer C also measures the speeds of trains Aand B to be 4/5 c and 3/5 c, respectively. Calculate the time it takes for train A to overtake train B asmeasured by a passenger on train B. By this we mean the time between the front of train A passingthe back of train B, and the back of train A passing the front of train B.

This is very straight forward problem which can be solved using special relativity concepts. The…

You travel from point A to point B in a car moving at a constant speed of 70 km/h. Then you travel the same distance from point B to another point C, moving at a constant speed of 90 km/h. Is your average speed for the entire trip from A to C 80 km/h? Explain why or why not.
High-speed motion pictures (3500 frames/second) of a jumping 230 μg flea yielded the data to plot the flea's acceleration as a function of time as shown in the figure ( Figure 1). (See "The Flying Leap of the Flea," by M. Rothschild et al. in the November 1973 Scientific American.) This flea was about 2 mm long and jumped at a nearly vertical takeoff angle.

cody is driving down the road, eastbound, with his dog in the back seat of the car. To an outside observer on the roadside, Cody’s speed is 21.0 meters per second. A blue car is passing them at a relative velocity of 2.5 meters per second. Which of the following statements are accurate about this situation? (Choose all that apply) The blue car’s velocity, to a roadside observer, is 23.5 m/s. The blue car’s velocity, to a roadside observer, is 18.5 m/s. The dog’s velocity, relative to Cody, is 0 m/s. Cody’s velocity, from the blue car’s frame of reference, is −2.5 m/s. Cody is stationary from the blue car’s frame of reference.
In 1 km races, runner 1 on track 1 (with time 2 min, 27.95 s) appears to be faster than runner 2 on track 2 (2 min, 28.15 s). However, length L2 of track 2 might be slightly greater than length L1 of track 1. How large can L2 - L1 be for us still to conclude that runner 1 is faster?
Can I please get some help with this problem. I can't seem to figure this out. thank you!
You are a construction worker standing still on 12th Ave N in Fargo, and you watch a minivan drive past at 25 mi/hr eastward. A kid in the back throws a ball at his brother in the front seat at 19 mi/hr. How fast does the ball move, as observed by you? (Positive indicates east, negative indicates west.) ? How fast does the ball move, according to the kid who threw it? If instead the kid in the front seat throws a rock at the kid in the back seat at 19 mi/hr, how fast would you observe the rock to travel?
