Which quantity best describes this description? justin walks at 3 miles per hour north, and then speeds up to 4 miles per hour.

(this is a question from ipc,)

i just wanted to check with

the answers are:

a. acceleration
b. velocity
c. inertia
d. speed

i went with acceleration, but it could also be velocity, since it's walking in a certain kind of direction.

i wanted to know if anyone else had thoughts, or if i should change my answer to b?

Personally, I agree with your answer, namely that the likely-intended event happening here is one of acceleration. Having said that, I also want to add: it pains me to see this type of wording because, clearly, it is vague and only invites confusion of the type you are talking about.

Good luck!

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
