Centripetal Force Physics Example 1

Solution

1. 1
   Recall the centripetal force formula: $$F_c = \frac{mv^2}{r}$$, where $m$ is mass, $v$ is speed, and $r$ is radius.
2. 2
   Identify the given values: $m = 0.5 \text{ kg}$, $v = 4 \text{ m/s}$, $r = 1.2 \text{ m}$.
3. 3
   Substitute and calculate: $$F_c = \frac{0.5 \times 4^2}{1.2} = \frac{0.5 \times 16}{1.2} = \frac{8}{1.2} \approx 6.67 \text{ N}$$
