M Karim Physics Numerical Book Solution Class 11 -

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.

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

A car travels from rest to a speed of 20 m/s in 5 seconds. What is its acceleration? m karim physics numerical book solution class 11

Given: $F = 20$ N, $m = 5$ kg, $a = 2$ m/s² Using the equation of motion: $$v = u

$$\mu = \frac{10}{5 \times 9.8} = 0.2$$

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. where $v$ is the final velocity
