A 1200-kg car pushes a 2100-kg truck that has a dead battery to the right. When the driver steps on the accelerator, the drive wheels of the car push against the ground with a force of 4500 N . What is the magnitude of the force the car applies to the truck?

Respuesta :

Answer:4500 N

Explanation:

Given

mass of truck [tex](m_t)=2100 kg[/tex]

mass of car[tex](m_c)=1200 kg[/tex]

as the car push the ground with a force of 4500 N so the force on the truck should also be 4500 N as they all the force is transmitted to push the truck

and their acceleration is

[tex]a=\frac{4500}{1200+2100}=1.36 m/s^2[/tex]
