How do you find The Speed IS Lens year after going a certain distance if you Have the mass, power, changes in gradient, distance Traveled?
Leopoldo Orejuela says...
A little vague, buthere goes:
Power = Energy/time
Change in Potential Energy = mass * gravity * change in gradient (By this did you mean change in elevation or change in slope.I'm going with change in elevation)
PE = MG*delE (delE = change in elevation)
Assuming no losses (friction, etc)
KE = PE
KE = MG*delE = 0.5 MV^2
0.5V^2 = G*delE
V^2 = (G*delE)/0.5
V = sqrt(G*delE)/0.5)
If "change in gradient"means change in slope I assume you have distances foe each slope segment ===>Do the trig to calculate the total change in elevation and solve as before.
