paco was driving his scooter west with an initial velocity of 4 m/s. he accelerates at 0.5 m/s² for 30 seconds. what is his final velocity?\n2 m/s\n8 m/s\n19 m/s\n60 m/s

Answer

Explanation:

Step1: Identify the formula

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

Step2: Substitute the given values

Given $u = 4\ m/s$, $a=0.5\ m/s^{2}$, and $t = 30\ s$. Substitute into the formula: $v=4 + 0.5\times30$.

Step3: Calculate the result

First, calculate $0.5\times30=15$. Then, $v=4 + 15=19\ m/s$.

Answer:

C. 19 m/s
