A car going at 30 m/s undergoes acceleration of 2 m/s^2 for 4 sec. What is its final speed? How far did it travel while it was accelerating?

Question

acceleration=the change in velocity/(divided by) the change in time

plz help thx

Answer 1

30m/s at 0 sec
30m/s + 2m/s (at 1 sec)
30m/s + 2m/s + 2m/s (at 2 sec)
etc.

Answer 2

The distance = (1/2)*(acceleration)*(time)^2 + (initial velocity)*(time).

Answer 3

what is the distance?
i got 184 is that correct?
the answer on my worksheet says 136...is this wrong or right?
PLZ HELP!!

Answer 4

136 is correct. Check your work.
