First, you need to calculate the resultant force:
R = m · a
= (12.3 + 5.1) · 1.5
= 26.1 N
Then, you can calculate the force of friction:
R = F - Fₐ
Fₐ = F - R
= 33 - 26.1
= 6.9 N
Now, we know that:
Fₐ = μ·m·g
Therefore we can solve for μ:
μ = <span>Fₐ/mg
= 6.9 / (17.4 · 9.8)
= 0.40
The coefficient of dynamic friction is </span>μ = <span>0.40

Answer:

Explanation:
given,
mass of the body = 40 Kg
speed in x-axis = 238 m/s
mass break into three part
m₁ = 7 kg
v₁ = 356 m/s (along the positive y axis)
m₂ = 4.5 kg
v₂ = 357 m/s(along the negative x axis)
m₃ = 40 - (7 + 4.5) = 28.5 Kg
v₃ = ?
using conservation of momentum
MV = m₁v₁ + m₂v₂ + m₃v₃
