Question

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?Calculate the magnitude of the force the car applies to the truck based on the information you collected in the Prepare step.

Answer 1

2,900 N is the answer if you need an explanation tell me and i will comment the explanation

Answer 2

2856 N

Step-by-step explanation:

We are given that

Mass of car=m=1200 kg

Mass of truck=M=2100 kg

Applied force=F=4500 N

Total mass=M'=1200+2100=3300 N

We know that

F=Ma

`4500=3300a`

`a=(4500)/(3300)=1.36m/s^2`

Force applied by car to the truck

`F_c=ma=2100* 1.36=2856 N`
