Top fuel dragster cars can accelerate from rest down a quarter mile track (400 meters) in under 4 seconds. Assuming constant acceleration, what would the acceleration of a dragster be if it sped down a track in exactly 4 seconds?
- a)75 m/s2
- b)100 m/s2
- c)50 m/s 2
- d)25 m/s2
Correct answer is option 'C'. Can you explain this answer?

We are given displacement and time, and we also know our initial velocity is 0, therefore we can use the formula: d = 1/2at2
We can plug in our values and solve for acceleration. 400m = ½ a 42
One trick to avoid having to calculate 800/16 mentally is to first divide both sides of the equation by 4, to simplify the equation to: 100m = ½ 4a. This of course gives us a = 50 m/s2.

Explanation:
Acceleration can be calculated using the equation:
\[a = \frac{v_f - v_i}{t}\]
Where:
- \(a\) = acceleration
- \(v_f\) = final velocity
- \(v_i\) = initial velocity
- \(t\) = time
Given that the dragster accelerates from rest, the initial velocity is 0 m/s. The final velocity can be calculated using the equation for distance traveled with constant acceleration:
\[d = \frac{1}{2} a t^2\]
Calculations:
- Distance, \(d\) = 400 meters
- Time, \(t\) = 4 seconds
Using the distance equation:
\[400 = \frac{1}{2} a (4)^2\]
\[400 = 8a\]
\[a = \frac{400}{8} = 50 \, m/s^2\]
Therefore, the acceleration of the dragster would be 50 m/s^2 if it sped down a track in exactly 4 seconds.
This acceleration is the correct answer as option 'C'.
