In the first 3 s after a car starts from rest with an acceleration of 4 m/s² it will travel A) 6 m. B) 12 m. C) 18 m. D) 72 m.

Question

Quizplus · Accepted Answer

The formula for distance traveled with constant acceleration is:

d = 1/2at^2

Where:
d = distance traveled
a = acceleration
t = time

Plugging in the values given in the problem:

d = 1/2(4 m/s^2) (3 s)^2
d = 18 m

Therefore, the car will travel 18 meters in the first 3 seconds. The correct answer is choice C: 18 m.
