m = 1.500 kg
Vo = 36 km/jam
Vt = 0 m/s
S = 50 m
ditanyakan : F ?
dijawab :
Vo = (36x1000)/3.600
= 36.000/3.600
= 10 m/s
Vt² = Vo² - 2 x a x S
0² = 10² - 2 x a x 50
0 = 100 - 100a
100 = 100a
a = 100/100
a = 1 m/s
jadi Gaya yg dibutuhkan :
F = m x a
= 1.500 x 1
= 1.500 N
36^2 = 0^2 + 2.a.50
a = 1296 : 100 = 12,96m/s^2
F = m.a
F = 1500 . 12,96 = 19440 N
