Explanation:
1. Using Newton's law of motion,
s = ut + (1/2) * a * t^2
1000 = (1/2) * 10 * t^2 [ taking acceleration due to gravity to be 10 m/s^2]
t = 10 \sqrt{2}
2
sec
2. Using Newton's law of motion,
v = u + at
v = 10 * 10 \sqrt{2}
2
v = 100 \sqrt{2}
2
m/s
3. One has to aim a little above the target and not exactly on the target while firing to account for the vertical displacement caused by acceleration due to gravity.
