Provide an appropriate response.If an object is dropped, the distance it falls after t seconds is given by d = 
gt2. A student is determining how long it would take an object to fall 23 feet on planet x having gravity 16 ft/sec2. The student determines the two solutions 
. Are both correct answers? Why or why not?
What will be an ideal response?
t = - 
gives negative time which is not correct.
