2. An athlete weighing 75 kg agrees to have his standing jump analyzed. Standing on a force plate, he crouches to lower his center of gravity, then executes a jump. The force plate measurement gives a reading that can be described by the equation F(t) = 480 sin t t + 160(1 t/t) where F(t) is in 1 bf. Here the push-off duration, t, is 180 ms. How high will your friend's center of gravity be elevated at the peak of his jump. Note: 1 lbf = 4.45 N (10 MARKS)
