tugas,,nii dua mobiil kapan ketemu?

Jika diketahui kedaan seperti di bawah ini:

mobil-berlawanan-arah

Maka hitunglah kapan kedua mobil tersebut 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
