v=v, +at Ax = v,t + ar? v = v, +2aAx A particle is standing on a cliff, 30m above the valley floor (see point A). It is observed that the particle is thrown vertically upward at a speed of 19.6m/s. a) How long does it take until the particle reaches the maximum height (to point B)? 2s b) What is the maximum height of the particle (from the valley floor)? 19.6m c) What is the acceleration of the particle at the maximum height? 98 m/s) d) Find the speed of the particle after 3s from its throwing. 8m/s e) How long does it take until the particle hits the valley floor (point C) (in short, we ask 19 6mi
