Hi I need some help please. If an object is given an initial velocity of v0 feet per second from a height of s0 feet, then it's height s after t seconds is given by the formula S= -16t^(2) + v[0]t + s[0]. If a pine cone falls from the top of a 112 foot tree then how many seconds does it take to reach the earth? Round the answer to one decimal place

    see the initial height is 112 m, let us assume it falls to the ground at time t, so the height at time t is 0 m
