You begin a race at rest and accelerate at a rate of 2 m/s² for 5 seconds. How far have you run? (Use the formula: d = 1/2 * a * t²)

a. 10 meters
b. 20 meters
c. 25 meters
d. 50 meters

Final answer:

The distance traveled after accelerating at 2 m/s² for 5 seconds is calculated using the equation d = 1/2 * a * t². Substituting the given values, the distance comes out to be 25 meters.

Step-by-step explanation:

The student's question involves calculating the distance traveled by an object that begins at rest and accelerates at a uniform rate. The formula to find the distance (d) in such a scenario is d = 1/2 * a * t² where 'a' is the acceleration and 't' is the time. Plugging in the values given in the question:

d = 1/2 * 2 m/s² * (5 s)²
d = 1/2 * 2 m/s² * 25 s²
d = 1 m/s² * 25 s²
d = 25 meters

Therefore, the distance the student has run after accelerating at a rate of 2 m/s² for 5 seconds is 25 meters, which corresponds to option (c).
