question 3 (1 point)
(02.02 mc)
a car increases from 10.0 km/s to 65.0 km/s in 5.0 seconds. calculate the average acceleration of the car during these 5.0 seconds.
a 11 km/s²
b 13 km/s²
c 15 km/s²
d 63 km/s²

Explanation:

Step1: Recall acceleration formula

The formula for average acceleration $a=\frac{v - u}{t}$, where $v$ is final - velocity, $u$ is initial - velocity, and $t$ is time.

Step2: Identify values

Here, $u = 10.0\ km/s$, $v = 65.0\ km/s$, and $t = 5.0\ s$.

Step3: Substitute values into formula

$a=\frac{65.0 - 10.0}{5.0}=\frac{55}{5.0}=11\ km/s^{2}$

Answer:

A. $11\ km/s^{2}$
