Question

required information. consider a runner traveling with an initial velocity of 3.4 m/s in the positive direction accelerates at a constant rate of 1.9 m/s² for a time of 5 seconds. note: this is a multi - part question. once an answer is submitted, you will be unable to return to this part. what is his velocity at the end of this time? the velocity at the end of 5 seconds is m/s.

Explanation:

Step1: Recall velocity kinematic formula

The formula for final velocity with constant acceleration is $v = v_0 + at$, where $v_0$ is initial velocity, $a$ is acceleration, and $t$ is time.

Step2: Substitute given values

$v_0 = 3.4\ \text{m/s}$, $a = 1.9\ \text{m/s}^2$, $t = 5\ \text{s}$
$v = 3.4 + (1.9 \times 5)$

Step3: Calculate the final value

$v = 3.4 + 9.5$

Answer:

12.9 m/s
