q2 needed

Q2) The distance (d) a free-falling object travels is calculated by the equation d=0.5gt2, where g is the acceleration of gravity ( g=9.81m/s2 on the earth, g=1.62m/s2 on the moon) and t is the time in free-fall. a) A skydiver opens his parachute after 5 seconds of free fall. How far does he travel just before deploying his parachute? b) If the maximum time allowed for skydiving before deploying the parachute is 10 seconds, what is the maximum distance he travels in free fall in the air? c) If this person is skydiving on the moon, how far does he travel in 5 seconds
