\[ s = v \cdot t = 16{,}67 \, \text{m/s} \times 7200 \, \text{s} = 120{,}024 \, \text{m} \]
ko kuma kimanin kilomita 120.
Motsin Layi Mai Sauri Daidaito (GLBB)

– \( v_0 \) shine saurin farko (m/s),
– \( a \) shine hanzari (m/s²),
– \( t \) lokaci ne (s).
2. Tsarin Nisa:
\[ s = v_0 \cdot t + \frac{1}{2} a \cdot t^2 \]
Ina:
– \( s \) shine nisan da aka yi tafiya (m).
3. Tsarin Sauri tare da Nisa:

Idan aka jefar da ƙwallon na tsawon daƙiƙa 3, saurinsa na ƙarshe shine:
\[ v = 0 + (9{,}8 \, \text{m/s}^2 \times 3 \, \text{s}) = 29{,}4 \, \text{m/s} \]
Nisan da ƙwallon ta yi a cikin daƙiƙa 3 shine:
\[ s = 0 \cdot 3 \, \text{s} + \frac{1}{2} \cdot 9{,}8 \, \text{m/s}^2 \cdot (3 \, \text{s})^2 = 44{,}1 \, \text{m} \]
