Question

If a car skids to a stop in 3.8s while undergoing a uniform acceleration of -9.55 m/s2, what is the car’s velocity?

Answer 1

36.29 m/s

Step-by-step explanation:

We know from theory that
`v= v_0 +a\Delta t`. Let's replace the value we know in our equation and solve for the only value left.

`0 = v_0 - 9.55 \cdot 3.8 \\ v_0 = 9.55 \cdot 3.8 = 36.29 m/s`
