a roller coaster accelerates from an initial velocity of 7.0 m/s to a final velocity of 70 m/s over 5 seconds. whats the acceleration in meters per second squared? report your answer to two decimal places rounded if necessary. do not include units.
Answer
Explanation:
Step1: Recall acceleration formula
The formula for acceleration $a=\frac{v - u}{t}$, where $v$ is final - velocity, $u$ is initial - velocity, and $t$ is time.
Step2: Identify given values
$u = 7.0$, $v = 70$, $t = 5$.
Step3: Substitute values into formula
$a=\frac{70 - 7.0}{5}=\frac{63}{5}=12.60$
Answer:
12.60
