Answer:
a)115 N
b)For father acceleration = 1.69 m/s²
For son acceleration = 3.28 m/s²
Explanation:
Given that
Mass of man(M)= 68 kg
Mass of son (m)= 34 kg
F= 115 N
As we know that from third law of Newtons ,It sates that every action have it reaction in opposite direction but same in magnitude.
So the force exerted by boy on father = 115 N
From Newtons second law of motion
F= m a
F=Force
m= mass
a=acceleration
For father
115 = 68 x a
a=1.69 m/s²
For son
115 = 35 x a'
a'=3.28 m/s²
Answer:
c) Calculate the magnitude of the forces acting on the middle carriage during acceleration.
This is the answer of this question ok.
Answer:
Yes.
Explanation:
51/17 is a rational number because "A number is considered a rational number if it can be written as one integer divided by another integer."
Calculation, add them. 0.85 x 5 = 4.25 Ω
