A mountain climber looks up a slope and sees an avalanche of boulders accelerating toward her. The boulders are initially60.0m above, moving at an initial speed of 2.00m/s and acceleratingat 4.00m/s^2. The climber reacts in 0.500sec. and begins torun down the mountain. At what speed must she run in order toreach the bottom of the slope, 30.0m below, before the boulders?
