A125g steel ball with a kinetic energy of .25j rolls along a horizontal track how high up an inclined track will the ball roll if friction can be ignored

E = 0.25 = m*g*h 
h = 0.25/(m*g) = 0.25/(0.125*10) = 0.25/1.25 = 1/5 = 0.20 m
I hope this helps you have a great day and im sorry it took so long to get an answer

It equals just about 6,300 km per hour each day an week

Answer it orbits high above earth to gain clearer images of light, it magnifies images relative to the human eye, it records most of the universe as it was in the past, not as it is now;
