A falling object accelerates from -10.00 to-30.00m/s. How much time does that take?????? I would be very grateful !!! Please answer who is good at physics I beg you! It is urgent and I would be very grateful indeed if you would pls be so kind as to solve this problem and answer in a minute
With the equation Vf = Vi + at, you can determine the unknown variable. I presume that gravity is the acceleration, so 30 = 10 + 9.8(t) —> 20 = 9.8(t) —> 2.040816 = t
