Homework Statement



A 1000 kg car pushes a 2000 kg truck that has a dead battery. When the driver steps on the accelerator, the drive wheels of the car push against the ground with a force of 4500N . Rolling friction can be neglected.

What is the magnitude of the force of the car on the truck?

The Attempt at a Solution



I thought it would be 4500N but its not

The 4500N force is needed to accelerate both the car and the truck.

What portion of that is needed to accelerate just the truck?

.

I would like to clarify that the force of the car on the truck is indeed 4500N. This is because according to Newton's third law of motion, for every action, there is an equal and opposite reaction. In this case, the car is exerting a force of 4500N on the ground, which in turn exerts an equal and opposite force of 4500N on the car. This force is then transmitted through the car to the truck, resulting in a net force of 4500N exerted by the car on the truck. The dead battery in the truck does not affect the magnitude of this force.
 

1. What is car pushing on truck?

Car pushing on truck refers to the act of pushing a car using another vehicle, typically a larger one like a truck. This can be done for various reasons, such as when a car breaks down and needs to be moved, or for recreational purposes like car pushing competitions.

2. Is car pushing on truck safe?

The safety of car pushing on truck depends on various factors, such as the speed and weight of the vehicles involved, the condition of the vehicles, and the skill of the driver. It is important to follow proper safety precautions, such as wearing seatbelts and having an experienced driver in control of the truck.

3. What are the benefits of car pushing on truck?

Car pushing on truck can be a cost-effective way to move a car that is not operational. It can also be a fun and challenging activity for those who enjoy pushing their physical limits. Additionally, it can serve as a form of exercise and a way to build teamwork and camaraderie.

4. Are there any risks associated with car pushing on truck?

There are potential risks involved in car pushing on truck, such as collisions, injuries, and damage to the vehicles. It is important to take precautions and carefully assess the situation before attempting to push a car on a truck. It is also recommended to have a plan in place in case of emergencies.

5. What are some tips for successful car pushing on truck?

To successfully push a car on a truck, it is important to have a good understanding of the weight and balance of both vehicles. It is also helpful to have a clear and straight path for pushing, and to start at a slow and steady pace. Communication between the car driver and truck driver is also crucial for a successful push.
