Question

Tolong bantu jawab ya... yg no.2

Answer 1

56.000per1,6=84.000per A
56.000A=134400
a=2,4

Answer 2

Asumsi:
masa Lokomotif (M) = 12000 kg
masa gerbong 1 (m1) = 44000 kg
masa gerbong 2 (m2) = 76000 kg
percepatan 1 (A) = 1,6 m/s²
percepatan 2 (a)  = ..... m/s²

Jawab:

Rumus perbandinga:
(M+m1)/A = (M+m2)/a
56000/1,6 = 88000/a
56000a = 88000 * 1,6
56000a = 140800
a = 140800/56000
a = 2,514 m/s²
