1: An object is dropped and its position vector, r, is given by

?? = (?? 5 – 2?? 2) ?? + (7?? 3 – 6?? 2) ??

a) Find the velocity, ??, and the acceleration, ??.
b) What is the angle between ?? and ?? when ?? = 2?

c) Model Q1 using MATLAB. Include a screenshot of the code and explain what each line of code is doing.
d) Give two advantages of MATLAB over manual calculations and support your answers with examples
