The giant sequoia redwood trees of the Sierra Nevada in California are said never to die from old age. Instead, an old tree dies when its shallow roots become loosened and the tree falls over. Removing a dead mature redwood from a forest is no easy feat, as the tree can have a mass of nearly 2.0x106 kg. Suppose a redwood with this mass is lifted 7.5 m with a net upward acceleration of 7.5x10–2 m/s2 . If the tree’s initial kinetic energy is zero, what is the final kinetic energy?
