Sebuah segitiga siku-siku ABC memiliki sisi AB = 12 cm dan sisi AC = 15 cm. Jika sudut B adalah sudut siku-siku, hitunglah panjang sisi BC

Tools used for this solution: Impulse = change in momentum Impulse = (force ) x (time applied) Momentum = (mass) x (speed)
Momentum of the ball after the kick = (mass)x(speed) = 0.43kg x 25 m/s = 10.75 kg-m/s .
Impulse exerted by the kicker's toe = 10.75 kg-m/s .
(force) x (time) = 10.75 kg-m/s .
Force x 0.001 sec = 10.75 kg-m/s .
Divide each side by 0.001 sec :
Force = (10.75 kg-m/sec) / (0.001 sec) = 10,750 kg-m/s² = 10,750 newtons .
That's about 2,416 pounds from the kicker's toe, during that ¹/₁₀₀₀ of a second.
(1.21 tons !)

The average force exerted on the football is approximately 10,750 newtons (N), calculated using the change in momentum and the duration of the impact. This was found by first converting the mass of the ball to kilograms and then applying the impulse-momentum theorem. The significant force shows the strength of the kick applied in a very short duration.

Jawaban:Karena segitiga ABC siku-siku di B, kita dapat menggunakan teorema Pythagoras: AB² + BC² = AC² Kita masukkan nilai yang diketahui: 12² + BC² = 15² 144 + BC² = 225 BC² = 225 - 144 BC² = 81 BC = √81 BC = 9 cm Jadi, panjang sisi BC adalah 9 cm.
