a person riding north on a bicycle speeds up from 0 m/s to 9 m/s in 3 seconds. the acceleration of the bicycle is m/s².
Answer
Explanation:
Step1: Recall acceleration formula
Acceleration $a=\frac{v - u}{t}$, where $v$ is final - velocity, $u$ is initial - velocity, and $t$ is time.
Step2: Identify given values
$u = 0\ m/s$, $v = 9\ m/s$, $t = 3\ s$.
Step3: Substitute values into formula
$a=\frac{9 - 0}{3}$.
Step4: Calculate the result
$a=\frac{9}{3}=3\ m/s^{2}$.
Answer:
$3$
