tugas 2,,mobiil balapan,,kapan ketemuu iia??

Jika diketahui keadaan seperti di bawah ini:

mobil-searah1

Maka hitunglah kapan kedua mobil itu bertemu?

Penyelesaian:

s = sA – sB

s = (VoA + ½ aA.t2) – (VoB + ½ aB.t2)

s = (VoA – VoB)t + ½ (aA – aB)t2

½ (aA – aB)t2 + (VoA – VoB)t – s = 0 x 2

(aA – aB)t2 + 2(VoA – VoB)t – 2s = 0
