From the fall of the snake, calculate the height of the building, if the velocity of the snake is 40m/sarrow_forwardIf a stone is dropped from the top of a tower with initial release velocity equal to zero, it falls a distance d in time t given by d = ½ gt2 where g is acceleration due to gravity (g = 9.8 m/s2). Its speed v at time t is given by v = gt. Suppose you go to the top of a tower and drop a stone. It hits the ground after 4.5 seconds. By how much does it drop in 1 second? How much is its displacement between 1 s and 2 s? What is the height of the tower?
