#### Answer:

#### Explanation:

GIVEN

#m_1=2 kg , m_2 =1kg# -
#"Coefficient of kinetic friction between " m_1 " and table" (mu_k)=0.15# -
# "Let"#

#color (blue) T " be tension on string"#

#" and " color(green) a" be the acceleration of the system "#

Now considering the forces on

Normal reaction

Resisting force of kinetic friction

Gravitational pull on

So for

Considering the forces on

Adding equation (1) and equation(2) we get
