An NCC parade is going at a uniform speed of 6 km/h through a place under a berry tree on which a bird is sitting at a height of 12.1 m. At a particular instant the bird drops a berry. Which cadet (give the distance from the tree at the instant) will receive the berry on his uniform ?

Answer» Explanation:Let t be the true time of FALL Initial velcoity=u=0m/sa=9.8 m/s2Distance=S=12.1 mS= ut+1/2 at²12.1=o+1/2 X 9.8x t²t²=12.1/4.9=2.46 sect=1.57 secCadet velocity=6km/hr=6x5/18=1.66 m/sDistance = SPEED x time=1.57 x 1.66 =2.6mThe CADET , at 2.6m away from the tree will receive the berry on his uniform.
