Problem #1: (Projectile Motion) A drone carrying a package to be delivered to customers. The package is to be release at the right moment to hit at specific location on the customers property, A. The drone is flying horizontally at an altitude of 100 m and velocity of 120 km/h A) At what angle 0 with the horizontal should the package be released to hit A? (hint find the horizontal distance between the drone and point A) B) What is the velocity of the package when it lands at A? v=120 km/h Pah of package 100 m

    Write a MATLAB Graphical User Interface (GUI) to simulate and plot the projectile motion – the motion of an object projected into the air at an angle. The object flies in the air until the projectile returns to the horizontal axis (x-axis), where y=0. This MATLAB program should allow the user to try to hit a 2-m diameter target on the x-axis (y=0) by varying conditions, including the lunch direction, the speed of the lunch, the projectile’s size, and the...
