Answer 1

fret - fengine - bu? = mudu 12350 - 0.86 02 = (1900) v dv udu - goo Jan 10 J 12350-03642 J 12350-0.8602 x-0 = 1900 en (12850-0.86 U²) - 2x0.86 € g0 - 12350-8.86v2 ge = - - 1104.65 la, 12350

v= 265 mph = 265x1609m 36008 = 118.44 mis 12350 - 0.86 (118.442) ? x = - 1104.65 lu 12350 x= 4160m = 4.16 km x < skom so before the Yes. end It will reach 265 mph of track. I
