select the correct answer. a motorcycle is moving at a constant velocity of 15 meters/second. then it starts to accelerate and reaches a velocity of 24 meters/second in 3 seconds. whats the acceleration of the motorcycle over this time? use a = (v - u)/t. a. 9 m/s² b. 8 m/s² c. 6 m/s² d. 5 m/s² e. 3 m/s²
Answer
Explanation:
Step1: Identify values
Initial velocity $u = 15$ m/s, final velocity $v=24$ m/s, time $t = 3$ s.
Step2: Apply acceleration formula
$a=\frac{v - u}{t}=\frac{24 - 15}{3}$.
Step3: Calculate the result
$\frac{24 - 15}{3}=\frac{9}{3}=3$ m/s².
Answer:
E. 3 m/s²
