Find the speed after 2 seconds? Find how far it traveled?

Resultant vector if travel 3 miles north and 4 miles east, find the resultant displacement --car goes from 10m/s to 22m/s in 3 seconds, find acceleration

Seriously, if you put half as much effort into simply reading your physics book as you do into copying all of your homework questions onto this forum, you'd find that this stuff is actually pretty simple.

Are you telling me you can't find an equation ANYWHERE that tells you how to calculate acceleration when you know the change in velocity and the change in time? And your book asks you to do vector addition without ever having explained how? I highly doubt that.

1. Don't expect direct answers from our members when it concerns homework question, because it's against the forum rules. Post your work, what you tried and what you don't understand. We'll help you with those.

2. Don't post many questions at a time in different boards. Since they fall under the same topic, you can post them once in a single thread.
