Question

Tolong siapapun yang bisa bantu saya please​

Answer 1

Jawaban:

1.

ΣF = ma

F - f - W sin 45 = ma

100 - f - 10*10*0,707 = 10*√2

f = 100 - 70,7 - 14,1

f = 15,2 N

f = μ N = μ W cos 45

15,2 = μ 10*10*0,707

μ = 15,2 / 70,7 = 0,2

2.

a sistem :

ΣF = ma

Wb - Wa = ma

mbg - mag = (ma+mb)a

3*10 - 2*10 = (3+2)a

10 = 5a

a = 2 m/s

Pada benda B berlaku :

ΣF = ma

Wb - T = ma

mbg - T = mb a

3*10 - T = 3*2

T = 30 - 6 = 24 N
