CAIE A-Level Physics AS 2.1.9 Motion Due to a Uniform Velocity in One Direction and a Uniform Acceleration Questions question 1

[Maximum number: 2]

Question (a)

(a)

A delivery company suggests using a remote-controlled aircraft to drop a parcel into the garden of a customer. When the aircraft is vertically above point P on the ground, it releases the parcel with a velocity that is horizontal and of magnitude 5.4 ms−15.4 \mathrm{~ms}^{-1}. The path of the parcel is shown in Fig. 2.1.
