Answer
given,
mass of car = 800 kg
mass of truck = 1900 kg
force acting = 4900 N
a) F = (mā+ mā ) a
[tex]a = \dfrac{F}{m_1+m_2}[/tex]
[tex]a = \dfrac{4900}{800+1900}[/tex]
a = 1.815 m/sĀ²
a) force exerted by Ā the car on the truck
Ā Ā [tex]F = m_{truck}\times a[/tex]
Ā Ā [tex]F = 1900\times 1.815[/tex]
Ā F = 3448.5 N
b) According to newtons third law
Force exerted by the truck on the car will be same.
Force of the truck on the car = Ā F = 3448.5 N
