Question

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

Answer 1

take s=0 , s[0] = 112 and v[0]=0

Answer 2

t = root7

Answer 3

?

Answer 4

what part dont u get?

Answer 5

What numbers I plug into the equation

Answer 6

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

Answer 7
