Solution Preview
Graphs are always helpful in understanding any phenomena. Just by going through the graph at a glance one can conclude to 1st order.
In modelling the motion, graphs are very helpful. Generally, graphs are drawn: displacement vs time, velocity vs time, acceleration vs time, velocity vs displacement etc.
For example take the case of uniform accelerating motion: model
i.e., a (acceleration) = constant
=> a = dv/dt = constant
In this case we can use three standard formulae;
v = u + a*t
s = u*t + (1/2)*a*t^2
v^2 = u^2 + 2*a*s
where, u is the ...

- " In question 2, you incorrectly add in the $3.00 dividend that was just paid to determine the value of the stock price using the dividend discount model. In question 4 response, it should have also been recognized that dividend discount models are not useful if any of the parameters used in the model are inaccurate. "
