Binary Stars Q1) A binary star system has a distance from Earth of 42.2 light years. The distance between the stars is 1.08 x 101 m and the rotation period is 104 days. Assume equal masses of the stars, and circular orbits (centre of mass of the system is at rest relative to the Earth). a) Calculate the speed of the stars relative to the centre of mass of the system. Further assume the...

1) As seen from Earth, what is
the speed, v, of ship B?
Express your answer using two significant
figures.
2) If ship A increases its speed by
0.10c relative to the Earth, does the relative speed
between ship A and ship B increase by 0.10c, by more than
0.10c, or by less than 0.10c? Explain.
3) Find the relative speed between ships A and B for the
situation described in part B.

In Newtonian mechanics, velocities add in an intuitive way: so if a launcher that can launch a ball horizontally at 20 m launches a ball forward while on a car moving at 30 m/s, the ball is launched at 50 m/s relative to the ground (you could say u = vtu', where u' is the velocity of object within the reference frame moving relative to the "lab", u is the velocity of the object in the lab frame, and v...

B. An observer in frame S sees lightning simultaneously strike two points 100 m apart.The first strike occurs at xi-50 m, yi-zi-ti-0 and the second at x2 -50 m, y2-z2 t2-0. (a) Find the coordinates of these two events in a frame S moving in the usual configuration at 0.9c along the x-axis of S. (b) How far apart are the events in S? (c) Find the difference in time between the events, as seen in S. Which event occurs...

A remote star is observed from the Earth to have a shape of an ellipspod of the longest axis length of 0.25 AU (parallel to x-axis), and is moving at a speed of 0.7 c relative to the Earth. The star is spherical in its rest frame. What axis could the star's velocity be parallel to? i. x-axis ii. y-axis jji. z-axis i only i and ii only ji and iii only all of the above Question 2 2 pts...

Two manned satellites approaching one another, at a relative speed of 0.150 m/s, intending to dock. The first has a mass of 3.50 x 10^3 kg, and the second a mass of 7.50 x 10^3 kg. (a) Calculate the final velocity (after docking) in m/s by using the frame of reference in which the first satellite was orginally at rest. (Assume the second satellite moves in the positive direction. Include the sign of the value in your answer.) (b) What...

3) Two particles fly apart in opposite directions in a laboratory. Particle A travels to the left at speed 0.06c, and particle B travels to the right at speed 0.09c (both speeds are relative to the laboratory). We wish to calculate the relative velocity of particles A and B using the Galilean transformation. a) Using a figure, show which object in this scenario defines the Home frame and which object defines the Other frame. [Hint: Be careful - in the...

Two manned satellites approaching one another, at a relative speed of 0.500 m/s, intending to dock. The first has a mass of 5.00 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. (a) Calculate the final velocity (after docking) in m/s by using the frame of reference in which the first satellite was originally at rest. (Assume the second satellite moves in the positive direction. Include the sign of the value in your answer.) (b) What...

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. The first has a mass of 4.00 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. If the two satellites collide elastically rather than dock, what is their final relative velocity? Adopt the reference frame in which the second satellite is initially at rest and assume that the positive direction is directed from the second satellite towards the first satellite....
