Question

A car accelerates from 13 m/s to 25 m/s in 6.0s. What was its acceleration? How far did it travel in this time? Assume constant acceleration.

Answer 1

Pay specific attention to significant figures, please.

Answer 2

v = u + at

u = 13, v = 25, t = 6

Answer 3

\[a=(a _{2}-a _{1} )/t\]

Answer 4

But the question really is, for the displacement, is the answer 114 m, or 1.1*10^2 m?

Answer 5

well you have to sig figs so i would go with the second one

Answer 6

two**
