Given: $v = 20$ m/s, $u = 0$ m/s, $t = 5$ s

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

Using the equation: $$f = \mu N$$, where $\mu$ is the coefficient of friction and $N$ is the normal reaction. Given: $v = 20$ m/s, $u = 0$

$$20 = 0 + a \times 5$$

$$a = \frac{20}{5} = 4$$ m/s²

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

Here, we will provide a sample solution to a few numerical problems from the M Karim Physics Numerical Book for Class 11. Given: $v = 20$ m/s
