Two stones are thrown simultaneously at a height of 436 meter. The first stone is thrown vertically downward at a speed of 8.3 meter per second, while the second stone is thrown vertically upward at the same speed. (Neglect air resistance, acceleration due to gravity is 9.8 m/s2). Find how long after the first stone hits the ground will the second stone hit the ground?
