(2-1)  Nefertiti is on the ground. She puts the shot so that its initial trajectory is parallel to the ground (she could do with a better coach), at an initial height of 1.20 m and a velocity of 10 ms-1 in the direction of the throw. The shot also falls downward under gravity, with an acceleration of 9.8 ms-2 in the downward direction.

①  Calculate the length of Nefertiti’s ground level put. You can ignore the effect of air resistance.

Now Nefertiti is on the plane, which is flying in a direction that will carry her directly over Cormorant's head at a velocity of 150 ms-1.  She puts in a forward direction along the axis of the plane and puts in exactly the same effort as she did when she threw on the ground earlier.
