Consider inertial observer A. Observer A measures the acceleration of spaceship A. Observer A is aboard a ship that sees Spaceship A moving with a velocity of +0.4c, and accelerating at 3.6 m/s 2 The mass of Spaceship A is 2 × 10^5 kg. Calculate the thrust force (in Newtons) of the Spaceship A’s engines according to observer A, both using the classical definition of force and the relativistic definition
A stick moves past an observer at a speed of 0.34c. According to the observer the stick is oriented parallel to the direction of motion and is 0.58 m long. 1) Determine the proper length of the stick. (Express your answer to two significant figures.) ____________ m
Consider a muon traveling at 0.950 c relative to a stationary observer. If the observer observes the muon for 0.300 s, how much time has passed in the muon's frame of reference? Consider a muon travelling at 0.950 c relative to a stationary observer. If the observer observes the muon travel 1.50 m, how far did the muon travel in the muon's frame of reference?
Two objects are traveling past an observer. Relative to the observer, the first object (A) appears to be traveling at 0.35 c in the +x direction. A second observer, in the frame of A, views the second object (B) traveling at 0.51 c in the -x direction. How fast would the original observer, view B as moving? Report you answer in units of 'c', and give your answer with 2 digits after the decimal point.
Problem 2 : Observer Design Consider the following observer: where A ,C The desired eigenvalues for the observer error dynamics matrix A LC are A1,2-10 t 10j. Is it possible to compute L to place these eigenvalues? Why or why not? If it is possible, compute I 1 10

An
observer is 20 feet above ground level
An observer is 20 feet above ground level on a bridge. The angle of depression from the observer to a car on the ground is 30 degreees. The angle of depression from the same observer to a bus in front of the car is 45 degrees. Find the distance from the car to the bus. (correct to the nearest tenth.)
Let two events occur at equal distances from an observer (O). The observer claims that two events will be simultaneous if light emitted from each event will reach me at the same time. Show that (maybe by drawing a picture) an observer (O') moving with respect to O will observe that these two events are not simultaneous. If two signals (say, from points A and B) reach observer O' simultaneously, what is their time sequence, as measured by O?
Two harmonic sound waves reach an observer simultaneously. The observer hears the sound intensity rise and fall with a time of 0.400 s between the maximum intensity and the succeeding minimum intensity. What is the difference in frequency of the two sound waves?
Observer is 3.0 m from a tiny light bulb and observer Bis 12.0 m from the same bulb. Assume that the light spreads out uniformly and undergoes no significant reflections or absorption. If observer B sees a light of intensity I, the light intensity that A sees is A) 361. BI C) 161. D) 1441. E) 91. standing wave is oscillating at 690 Hz on a string, as shown in the figure. What is the speed of veling waves on...
