Two events occur in an inertial system at the same time, but distance Do apart. In another inertial system, moving relative to the first with velocity , the two events are observed to be separated by distance D. The direction of is parallel to the line between the two events. What is the time difference between the two events in the second inertial system? Do = 4970 km; D = 9400 km;

James (mass 81.0 kg) and Ramon (mass 57.0 kg) are 20.0 m apart on a frozen pond. Midway between them is a mug of their favorite beverage. They pull on the ends of a light rope stretched between them. Ramon pulls on the rope to give himself a speed of 1.10 m/s. What is James's speed? It must have the proper dimensions of speed.

At a particular instant, in a coordinate frame chosen by us, the Earth (mass = 6 x 1024 kg) is at location (-7.30 × 106, -7.80 × 106, 3.73 × 106) m and the Moon (mass = 7 x 10²² kg) is at location (-1.35 × 108, -2.50 × 10³, 2.82 × 108) m. A satellite with mass 5000 kg is at location (-1.18 × 10³, -2.73 × 10³, 3.10 × 108) m. What is the net force on the satellite? Assume that the gravitional force of the Sun is negligible. net = i i !)N

You are the pilot of a spacecraft intended for travel at very high speeds. Before leaving you measure the spacecraft to be 31.4 m long and have a mass of 5.28 x 104 kg. During your travel, you pass a planet and exchange information with an observer on the planet. You are told that your spacecraft has been measured to be 28.6 m long. a. How fast is your spacecraft travelling with respect to the planet? b. You are told there is a nearby planet that is stationary with respect to the first planet. The observer on the first planet says it will take you 25 s to reach the nearby planet. How far away does your co-pilot on the spacecraft say the nearby planet is? c. How much energy was required to accelerate your spacecraft to this speed?

Two manned satellites approaching one another, at a relative speed of 0.200 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.)  m/s   b. What is the loss of kinetic energy (in J) in this inelastic collision?  J   c. Repeat both parts by using the frame of reference in which the second satellite was originally at rest. final velocity (m/s) m/sloss of kinetic energy (J) J   Explain why the change in velocity is different in the two frames, whereas the change in kinetic energy is the same in both.

F The force F = 460 N acts on the frame. Resolve this force into components acting along members AB and AC, and determine the magnitude of each component. Given that a = 34° and ß = 47°, The magnitude along AB is (round to one decimal place): The magnitude along AC is (round to one decimal place): N

The Starship Enterprise returns from warp drive to ordinary space with a forward speed of 51 km/skm/s . To the crew's great surprise, a Klingon ship is 140 kmkm directly ahead, traveling in the same direction at a mere 30 km/skm/s . Without evasive action, the Enterprise will overtake and collide with the Klingons in just about 6.7 ss . The Enterprise's computers react instantly to brake the ship. What magnitude acceleration does the Enterprise need to just barely avoid a collision with the Klingon ship? Assume the acceleration is constant.

Consider a binary star system that has bright lines at 656.72 and 656.86 nm,56.46-nm hydrogen line in the rest frame, estimate the speed V of the center of mass of the binary system is 151km/s how do I determine the mass of each star, they orbit in a circular motion.
