A stone is dropped from rest from a balcony while, at the same instant, a second stone is thrown vertically downward from the same point with a speed of 5 m/s5\,\text{m/s}. Take g=10 m/s2g = 10\,\text{m/s}^2. (i) Calculate the speed of each stone after 3 3\,s. (ii) Which stone has the greater speed at that instant?
