equations:

1. calculate the acceleration of josh riding his bicycle in a straight line that speeds up from 4 m/s to 6 m/s in 5 seconds.

Explanation:

Step1: Identify known values

Initial velocity $v_i = 4\ \text{m/s}$, final velocity $v_f = 6\ \text{m/s}$, time $t = 5\ \text{s}$

Step2: Use acceleration formula

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

Step3: Substitute values into formula

$$a = \frac{6 - 4}{5}\ \text{m/s}^2$$

Step4: Calculate the result

$$a = \frac{2}{5} = 0.4\ \text{m/s}^2$$

Answer:

$0.4\ \text{m/s}^2$
