Here, we will provide a sample solution to a few numerical problems from the M Karim Physics Numerical Book for Class 11.
Given: $F = 20$ N, $m = 5$ kg, $a = 2$ m/s²
$$10 = \mu \times 5 \times 9.8$$
$$20 - f = 5 \times 2$$
$$\mu = \frac{10}{5 \times 9.8} = 0.2$$
$$f = 20 - 10 = 10$$ N
Given: $v = 20$ m/s, $u = 0$ m/s, $t = 5$ s 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.
