Question

Tolong dong bantu nih bsk dikumpul.,. Plissssssssssss

Answer 1

M = 10 kg
F1 = 10 N ke timur
F2 = 35 N ke selatan
F3 = 10 N ke barat
F4 = 5 N ke utara

Fx = F1 - F3 = 10 - 10 = 0
Fy = F2 - F4 = 35 - 5 = 30 N (arah selatan)

F = m . a
30 = 10 . a
a = 30/10 = 3 m/s²

Jawaban D

--------------

m = 10 kg
F = 20 N
vo = 3 m/s
t = 4s

F = m . a
20 = 10 . a
a = 20/10 = 2 m/s²

vt = vo + at
v(4) = 3 + 2 . 4
v(4) = 3 + 8 = 11 m/s
