Question

4 bicycle ride
a cyclist increases speed from 4 m/s to 10 m/s in 3 seconds. what is the acceleration?

$a=\frac{v_f - v_i}{t}=$

Explanation:

Step1: Identify initial and final velocities and time

Initial velocity $v_i = 4\ m/s$, final velocity $v_f=10\ m/s$, time $t = 3\ s$.

Step2: Apply acceleration formula

The formula for acceleration $a=\frac{v_f - v_i}{t}$. Substitute the values: $a=\frac{10 - 4}{3}$.

Step3: Calculate the acceleration

$a=\frac{6}{3}=2\ m/s^2$.

Answer:

$2\ m/s^2$
