Dexter needs to monitor the movement of a rover vehicle on mars for one year. which technologies should dexter use for tracking purposes? check all that apply. telescopes that show where the rover vehicle is located satellites that collect information about rover vehicle distance space stations that store real-time data about rover vehicle speed computer simulations that model how long it takes the rover to get to mars doppler radar that records information about weather the rover is exposed to

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!
