Question

soccer ball kick
a soccer ball is at rest. a player kicks it and it reaches a speed of 12 m/s in 2 seconds. what is the acceleration?
a = \frac{v_f - v_i}{t} =

Explanation:

Step1: Identify initial and final velocities and time

Initial velocity $v_i = 0$ m/s (at rest), final velocity $v_f=12$ m/s, time $t = 2$ s.

Step2: Apply acceleration formula

The formula for acceleration $a=\frac{v_f - v_i}{t}$. Substitute the values: $a=\frac{12 - 0}{2}$.

Step3: Calculate the acceleration

$a=\frac{12}{2}=6$ m/s².

Answer:

6 m/s²
