Observer O sees a red flash of light at the origin at t = 0 and a blue flash of light at x = 3.19 km at a time t = 7.56 μs. What are the distance and the time interval between the flashes according to observer O', who moves relative to O in the direction of increasing x with a speed of 0.630c? Assume that the origins of the two coordinate systems line up at t = t' = 0. distance km time interval μs
(1) Observer S (at x 0) sees a flash of red light at XR 1200 m from her position and a flash of blue light at x,-480 m on the same straight line. She measures the time interval between the flashes to be 5 us, with the blue flash occurring first (that is, ted ue 5 Hs.) What is the velocity v of observer S' who records the flashes as occurring at the same place, that is, who measures Ax...
2. An observer S sees a flash of red light 1200 m from his position and a flash of blue light straight line. He measures the time interval between 720 m closer to him and on the same the occurrences of the flashes to be 5 microseconds, the red flash occurring first. a. What is the relative velocity v of a second observer S' who would record these flashes as occurring at the same place? b. From the point of...
A red light flashes at position x - 3.00 m and time t, - 1.00 x 10's, and a blue light flashes at x = 4.10 m and t = 9.74 x 10's, all measured in the reference frame. Reference frame S'moves uniformly to the right and has its origin at the same point as sattuto. Both flashes are observed to occur at the same place in S. (a) Find the relative speed between S and S. m/s (b) Find...
System S' has a velocity u = +0.58 c relative to system S, as shown. The clocks of S and S' are synchronized at t = t' = 0 s when the origins 0 and 0' coincide. An event is observed in both systems. The event takes place at x = 600 m and at time t = 8 μs, as measured by an observer in S. In the figure, the x'-coordinate of the event, measured by an observer in...
A rhinoceros is at the origin of coordinates at time t 1 =0 . For the time interval from t 1 to t 2 = 14.5 s , the rhino's average velocity has x-component -3.2 m/s and y-component 5.7 m/s . a>At time t 2 = 14.5 s what is the x-coordinate of the rhino? b>At time t 2 = 14.5 s what is the y-coordinate of the rhino? c>How far is the rhino from the origin?
5. (Fully graded)An observer in frame S sees lightning simultaneously strike two points 100 m apart. The first strike occurs at zi = V1 =句= t,-0 and the second at z2 = 100m, y2 = 뀨2 = t2 = 0. (a) What are the coordinates of these two events in a frame S" moving at 0.70c in the positive x direction relative to S? b) How far apart are the events in S? (c) Are the events simultaneous in S?...
Version 1 0.) Red light propagates through window glass at a speed of 2.0 x 10 m/s. This means that bli light must propagate through vacuum at a speed of: A) 1.5 x 10 m/s B) 2.0 x 10 m/s C) 2.5 x 10 m/s D) 3.0 x 10 m/s E) No way to know with the information given, but it must be <3.0 x 10 m/s A screen red, yellow, blue glass 7.) Red, yellow, and blue light along...
A particle starts from the origin at t = 0 and moves along the positive x axis. A graph of the velocity of the particle as a function of the time is shown in the figure; the v-axis scale is set by vs = 6.0 m/s. (a) what is the coordinate of the particle at t = 5.0 s? (b) what is the velocity of the particle at t = 5.0 s? (c) what is the acceleration of the particle...
please answer all questions For 1 2 0, a particle moves along the r-axis. The velocity of the particle at time t is given by r(t)-1 + 2sin(2) Theparticle is atposition x = 2 attimet=4. (a) At time t-4, is the particle speeding up or slowing down? (b) Find all times t in the interval o<t<3 when the particle changes direction. Justify your answer. (c) Find the position of the particle at time t 0. (d) Find the total distance...
A car is initially stopped, vco = 0, at a traffic light whose position we will use as our origin, x = 0. The light turns green at time t = 0 and the car starts moving with constant acceleration ac = 2 m/s2 . At that same instant, the front of a truck traveling at constant speed vt = 15 m/s passes the front of the car. After a time tD and distance x = D, the accelerating car...
