Question

jamil kicks the ball into the net at a distance of 18.4 m in 0.46 s. what was the average speed of the ball? 29.8 m/s 40 m/s 8.5 m/s 4 m/s

Explanation:

Step1: Recall speed formula

The formula for average speed is $v = \frac{d}{t}$, where $d$ is distance and $t$ is time.

Step2: Substitute values

Given $d = 18.4$ m and $t=0.46$ s, we substitute into the formula: $v=\frac{18.4}{0.46}$.

Step3: Calculate result

$\frac{18.4}{0.46}=40$ m/s.

Answer:

B. 40 m/s
