Initial speed of Gazelle is along x direction and its value will be

also its initial height is given as

Part a)
now from kinematics along Y direction

as we know that





Part b)
distance moved horizontally

as we know that

now we will have

so it will lend at distance of 4 m.
Part c)
final velocity in vertical direction



so net speed will be
