W = 16 N
a = 4 m/s²
μ = 0,5
dit : F ?
dijawab :
massa :
W = m x g
16 = m x 10
m = 16/10
= 1.6 kg
Gaya gesek :
Fg = μ x m x g
= μ x (mxg)
= μ x W
= 0,5 x 16
= 8 N
jadi gaya Horizontal :
F - Fg = m x a
F - 8 = 1,6 x 4
F - 8 = 6,4
F = 6,4 + 8
F = 14,4 N
m=16/10
m=1,6 Kg
a=4m/s²
Koefisien=0,5
∑F=ma
F-fg=ma
F-16.0,5=1,6X4
F=8+6,4
F=14,4 N
