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
