5. a. Diketahui : m₁ = 2 kg

m₂ = 2 kg

F = 8 N

Ditanya: a. a = ....... ?

b. T = ......... ?

Jawab : a. a = F /( m₁ + m₂ )

= 8/( 2 + 2 )

= 8/4

= 2 m/s²

b. ΣF₂ = m₂.a

F - T = 2.2

8 - T = 4

8 - 4 = T

T = 4 N

b. Diketahui : m₁ = 3 kg

m₂ = 2 kg

g = 10 m/s²

Ditanya : a. a = .......?

b. T = ......?

Jawab : a. W₁ = m₁.g

= 3.10 = 30 N

W₂ = m₂.g

= 2.10 = 20 N

a = W₁ - W₂/( m₁ + m₂ )

= ( 30 - 20 )/( 3 + 2 )

= 10/5

= 2 m/s²

b. ΣF₂ = m₂.a

W₂ - T = 2.2

20 - T = 4

20 - 4 = T

T = 16 N

c. Diketahui : m₁ = 2 kg

m₂ = 3 kg

μk = 0,3

Ditanya : a. a = ......?

b. T = ......?

Jawab : a. a = ( m₂ - μk.m₁ )g/( m₁ + m₂ )

= ( 3 - 0,3.2 ).10/( 2 + 3 )

= ( 3 - 0,6 ).10/5

= 2,4.2

= 4,8 m/s²

b. T = m₁.a + μk.m₁.g

= 2.4,8 + 0,3.2.10

= 9,6 + 6

= 15,6 N
