zaiden received the following problem: a particle moves in a straight line with velocity v(t) meters per second (graphed), where t is time in seconds. at t = 6, the particles distance from the starting point was 5 meters in the positive direction. what is the particles displacement between t = 6 and t = 9 seconds? which expression should zaiden use to solve the problem?
Answer
Explanation:
Step1: Recall displacement - velocity relation
Displacement from $t = a$ to $t = b$ is given by $\int_{a}^{b}v(t)dt$. Here $a = 6$ and $b = 9$.
Step2: Write the required integral
The expression for the particle's displacement between $t = 6$ and $t=9$ seconds is $\int_{6}^{9}v(t)dt$.
Answer:
$\int_{6}^{9}v(t)dt$
