If something is 167,700 feet less than something then the value of the longer object would be the that much more than the length of that shorter object. In this case it would be 373,000 + 167,700 = 540,700 ft.
H=0 Therefore: 144t-16t²=0 t (144-16t)=0 We have two equations: 1) t=0 (when the ball is released) 2) 144-16t=0 -16t=-144 t=-144 / -16=9 (this is the time )
