Question

A race car's velocity decreases from 36 m/s to 15 m/s over a 3.0 s period, what is the average acceleration? A race car's velocity decreases from 36 m/s to 15 m/s over a 3.0 s period, what is the average acceleration? @Physics

Answer 1

average acceleration = change in velocity / change in time.

Answer 2

I did the problem and got -63m/s(squared). Is this correct?

Answer 3

\[\frac{v_f - v_1}{\Delta t} = \frac{15 - 36}{3} = -7\]

Answer 4

\[\frac{Vfinal-Vinitial}{t}=-7m/s^2\]\[\frac{15m/s-36m/s}{3.0s}=-7m/s^2\]
