That is correct, but only one of them is valid.

Remember that there is T for which the speed is constant, and this lies between and

So and express it in terms of V. Try both values of V and you will see that one of them does not make sense, hence you get left with one.

Omg that's what I got whoop whopp
6. Honestly think I'd personally learn better from just looking at a full solution...
But I guess the forum rules do make sense, as people could use it as a cheating mechanism, however I'd work better with full solutions just saying maybe the rule could be refined or something, like to get a full solution answer, you must show a reasonable attempt, and then only can people reply with full solutions
