Two stones are thrown off a cliff with the same velocity (20 m/s) at the same time. The first stone is thrown at an angle 40 degrees upward from the horizon and the second is thrown 30 degrees downward from the horizon. both are thrown in the same compass direction, only the angles of elevation of the throws differ.

b. which stone lands first and by how many seconds before the other one?
