Numerical Problems

Numerical problems are essential tools for reinforcing theoretical knowledge and developing practical problem-solving skills. Below are examples of key physics concepts applied to real-life situations:

1. Average Speed
   1. Example: A sprinter completes a 100-meter race in 12 seconds.
   2. Solution: Vavg=DistanceTime=10012=8.33 ms−1V_{\text{avg}} = \frac{\text{Distance}}{\text{Time}} = \frac{100}{12} = 8.33 \, \text{ms}^{-1}Vavg​=TimeDistance​=12100​=8.33ms−1
2. Acceleration
   1. Example: A car accelerates uniformly from rest to 20 ms−120 \, \text{ms}^{-1}20ms−1 in 8 seconds.
   2. Solution: a=vf−vit=20−08=2.5 ms−2a = \frac{v_f – v_i}{t} = \frac{20 – 0}{8} = 2.5 \, \text{ms}^{-2}a=tvf​−vi​​=820−0​=2.5ms−2
3. Free Fall
   1. Example: A stone dropped from a height hits the ground in 5 seconds.
   2. Solution:
      • Using the formula for height: h=12gt2=12(10)(5)2=125 mh = \frac{1}{2} g t^2 = \frac{1}{2} (10)(5)^2 = 125 \, \text{m}h=21​gt2=21​(10)(5)2=125m
      • Final velocity: vf=gt=(10)(5)=50 ms−1v_f = g t = (10)(5) = 50 \, \text{ms}^{-1}vf​=gt=(10)(5)=50ms−1
