An observer at rest on the Earth observes two spacecraft moving
toward one another. Spacecraft 1 travels to the right at a velocity
of 0.71 c relative to the observer. Spacecraft 2 travels to the
left at a velocity of 0.71 c relative to the observer. What is the
velocity of Spacecraft 1 relative to Spacecraft 2 (give your answer
in terms of “c”)? Make sure that you draw a diagram and
that you label S, S’, ux, ux’, and
v. Also, remember that velocity is a vector.

A neutron travels to the right at a velocity of 0.63 c relative to an observer at rest on the surface of the Earth (sometime called the “Laboratory Frame”). An alpha particle travels to the right at a velocity of 0.75 c relative to the moving neutron. What is the velocity of the alpha particle relative to the observer at rest on the surface of the Earth (give your answer in terms of “c”)? Make sure that you draw a...
These are the answers, please provide the work for the calculation 1. Two cells that subdivide on Earth every 10.0s start from the Earth on a journey to the Sun (1.5 x 1011 m away) in a spacecraft moving at 0.850c. How many cells wil exist when the spacecraft crashes into the Sun? Earth time is 588s. Spacecraft time is 310s or 31 cycles of division. 2312.1x 10 cells at the end of the journey. 2. As a spacecraft moving...
The spaceship Enterprise 1 is moving directly away from earth at a velocity that an earth-based observer measures to be +0.69c. A sister ship, Enterprise 2, is ahead of Enterprise 1 and is also moving directly away from earth along the same line. The veolcity of Enterprise 2 relative to Enterprise 1 is +0.45c. What is the velocity of Enterprise 2, (in terms of c) as measured by the earth-based observer?
While the wind is blowing due East at 87 km/hr relative to the ground, a jet travels due North at 562 km/hr relative to the wind (the air). Obviously, the wind will push the jet eastward and throw the jet off course. What is the velocity of the jet relative to the ground? Before you do any calculations, make sure that you draw a diagram that shows reference frames S and S', Also, make sure that you label the velocities...
A car travels East at a constant velocity of 83 km/hr relative to the ground. A truck travels West at a constant velocity of 51 km/hr relative to the ground. What is the velocity of the truck relative to the car (enter the magnitude and direction separately)? Before you do any calculations, make sure that you draw a diagram that shows reference frames S and S'. Also, make sure that you label the velocities u, u', and v in your...
Question B4 Figure QB4 shows a spacecraft which is moving through space at a constant velocity. The xyz axes are fixed to the craft. At the instant under consideration, the craft has a constant rotation of 1 radis about the z axis, the solar panels are at an angle of 30° to the z axis and is increasing at the constant rate of radis. (a) Determine the vector expression of the angular acceleration of the right hand panel. (4 marks)...
25. mmh Two protons are moving directly toward one another. When. they are very far apart, their initial speeds are 3.00 x 10 m/s. What is 38. rest at th plate cap the distance of closest approach?
One object is at rest, and another is moving. The two collide in a one-dimensional, completely inelastic collision. In other words, they stick together after the collision and move off with a common velocity. Momentum is conserved. The speed of the object that is moving initially is 29 m/s. The masses of the two objects are 3.4 and 7.7 kg. Determine the final speed of the two-object system after the collision for the case (a) when the large-mass object is...
One object is at rest, and another is moving. The two collide in a one-dimensional, completely inelastic collision. In other words, they stick together after the collision and move off with a common velocity. Momentum is conserved. The speed of the object that is moving initially is 24 m/s.

(20 pts) On a frictionless, horizontal air table, puck A (with mass 0.15 kg) is moving toward puck B (with mass 0.3 kg), which is initially at rest. After the collision, puck A has a velocity of 0.11 m/s to the left, and puck B has a velocity of 0.65 m/s to the right. (a) What was the speed of puck A before the collision? (b) Calculate the change in the total kinetic energy of the system (A and B)...
