Week-4 Challenge WOT Condition Part-2

For question no 2,3 & 4 i need some help so i fixed a one on one session with technical experts, and he informed me that except question no.1 all other questions required powertrain blockset and it is accessible only in full version of Matlab, and i am using a trial version as suggested in the very first video of course, and he ask me to search on internet for the full version of Matlab but i didnt found it so i am submitting my challenge with only question 1.
