Final answer:
To find the acceleration of a motorcycle that goes from 0 m/s to 75 m/s in 25 seconds, use the average acceleration formula, resulting in an acceleration of 3 m/s^2.
Step-by-step explanation:
The acceleration of a motorcycle that accelerates from 0 m/s to 75 m/s in 25 seconds can be found using the formula for average acceleration, which is the change in velocity divided by the time it takes for the change to occur. In this case, the initial velocity (v_i) is 0 m/s, the final velocity (v_f) is 75 m/s, and the time (t) is 25 seconds. The formula used is:
a = (v_f - v_i) / t
By plugging the values into the formula, we get:
a = (75 m/s - 0 m/s) / 25 s = 3 m/s2
Therefore, the correct answer is B. 3 m/s2.
