The only way I can see how to do it without integration is taking the average velocity and then multiplying by the time. But this would only give you an approximation.
I think they want you to use integration hence they have specified an initial condition for the body's displacement- indicating that the constant is zero. Also note that the acceleration is not uniform as the velocity function forms a parabola- so we can't use shape formulas like area of a...
I'd just rest up and psychologically prepare yourself for the rest of the year. In my opinion having a good mindset will help you achieve a much better result than hours and hours of studying.
In the summer holidays I did some light study for both 3U and 2U but really focused on other aspects...
Thanks very much for the detailed response- I’m still very keen to follow aerospace as a career path but will keep in mind that like most things in life, it is very much crystallised. I will just see where it takes me and be prepared for anything. Final question- would you still follow the same...
