1 AnswerMathematics7 years agosuppose that a hight of an object as a function of time is given by f(t)= at^2 + bt + c?
suppose that a hight of an object as a function of time is given by f(t)= at^2 + bt + c, where t is time in seconds, and a,b, and c are certain constants. If, after 1,2, and 3 seconds, the corresponding heights are 188ft, 140ft, and 60ft, respectively, find the time at which the object is at ground level (height=0).
