Spacecraft a is in an elliptical earth orbit having the following orbital elements: e = 0.1, ω = 40°, i = 60°, ω = 30° and θ = 50° , h = 65,000 km2 /s and spacecraft b is in a nearly circular earth orbit with the following orbital elements: e = 0.02, ω = 20°, i = 20°, ω = 110° and θ = 40° , h = 61,000 km2 /s a) determine the relative position, velocity and acceleration of spacecraft b relative to a, measured in local vertical/local horizontal commoving coordinate system of spacecraft a. b) plot the two orbits and show the location of each satellite in the geocentric equatorial frame

If jill was traveling at 300 miles in 4 hours due south what was his velocity in miles per minute a) 75 miles per hour due south b) .02 miles per second due south c) .5 miles per second due south d) 1 mile per hour due south

How much force must a locomotive exert on a 12840-kg boxcar to make it accelerate forward at 0.490 m/s2?

A23 kg log of wood begins from rest, 300 m up a sluice (a water track used to transport logs, think of it as an inclined plane with negligible friction) inclined at 20° to the horizontal. after it reaches the flat waterway at the bottom it collides elastically with a 100 kg block of wood initially at rest near the base of the incline. (a) how long does it take the 23 kg log to travel down the incline? (b) what is the speed of the 23 kg log at the bottom of the incline? (c) what are the velocities of both blocks of wood after the collision? (d) what is the total kinetic energy before the collision? (e) what is the kinetic energy of the 23 kg log after the collision? (f) what is the kinetic energy of the 100 kg block of wood after the collision? (g) what is the total kinetic energy after the collision? (h) compare the total initial and total final kinetic energies. is this consistent with what you would expect for elastic collisions? explain!
