Solution to Numerical Problems
Here, we will provide a sample solution to a few numerical problems from the M Karim Physics Numerical Book for Class 11.
Problem 1: A car travels from rest to a speed of 20 m/s in 5 seconds. What is its acceleration?
Solution: 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.
Given: $v = 20$ m/s, $u = 0$ m/s, $t = 5$ s
$$20 = 0 + a \times 5$$
$$a = \frac205 = 4$$ m/s²
Problem 2: A block of mass 5 kg is placed on a horizontal surface. A force of 20 N is applied to the block, causing it to move with a uniform acceleration of 2 m/s². What is the coefficient of friction between the block and the surface?
Solution: 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.
Given: $F = 20$ N, $m = 5$ kg, $a = 2$ m/s²
$$20 - f = 5 \times 2$$
$$f = 20 - 10 = 10$$ N
Using the equation: $$f = \mu N$$, where $\mu$ is the coefficient of friction and $N$ is the normal reaction.
$$10 = \mu \times 5 \times 9.8$$
$$\mu = \frac105 \times 9.8 = 0.2$$
