Question

starting from rest, a drag racer must travel 402 meters in less than 3.9 seconds in order to qualify for the finals. If a drag racers final velocity is 214 m/s, will they qualify for the finals?

Answer 1

Given

x: distance

x = 402 m

t: time

t = 3.9 s

Procedure

We are going to calculate the minimum speed necessary to win the race.

`\begin{gathered} v=(x)/(t) \\ v=(402)/(3.9) \\ v=103.076\text{ m/s} \end{gathered}`

As the final velocity was 214 m/s which is greater than 103 m/s.

The drag racer will qualify for the finals
