$$20 = 0 + a \times 5$$
Here, we will provide a sample solution to a few numerical problems from the M Karim Physics Numerical Book for Class 11.
$$\mu = \frac{10}{5 \times 9.8} = 0.2$$
A car travels from rest to a speed of 20 m/s in 5 seconds. What is its acceleration?
$$f = 20 - 10 = 10$$ N
$$a = \frac{20}{5} = 4$$ m/s²
$$20 - f = 5 \times 2$$
Given: $F = 20$ N, $m = 5$ kg, $a = 2$ m/s²
