Consider the plot below describing the acceleration of a particle along a straight line with an initial position of 10 m and an initial velocity of 9 m/s.

1. What is the velocity at 7 s?
2. What is the position at 7 s?

Please help me! I got the answer -12 for #1 and -0.5 for #2, but the computer's telling me these are wrong (it's an online worksheet). I don't understand why?

Well you can use the two default equations.
[tex]v=v_o +at[/tex]
You'll have to use each equation twice for each problem though.
