Using the equation of motion: $$v = u + at$$, where $v$ is the final velocity, $u$ is the initial velocity, $a$ is the acceleration, and $t$ is the time.

$$a = \frac{20}{5} = 4$$ m/s²

Using Newton's second law of motion: $$F - f = ma$$, where $F$ is the applied force, $f$ is the frictional force, $m$ is the mass, and $a$ is the acceleration.

$$10 = \mu \times 5 \times 9.8$$

$$f = 20 - 10 = 10$$ N

$$20 - f = 5 \times 2$$
