# Calculating the push force on a vehicle

Hi,

I am trying to work out what force you would need to push a four wheel vehicle of mass 200kg from rest to a top speed of 2m/s (acceleration 1m/s2) and the force needed to maintain that top speed . I am not sure how to go about this, do i just consider rolling resistance and take that as 0.01...does static friction come in somewhere?

thanks!

Simple F=ma. If you want to account for friction, I don't know, .01 sounds like a good number.

I wouldn't worry about static friction. The force needed to accelerate as fast as you want is MUCH greater than the static friction, and the static friction can only hold you back before you even start accelerating...

## What is the formula for calculating the push force on a vehicle?

The formula for calculating the push force on a vehicle is force = mass x acceleration. This means that the force exerted on a vehicle is directly proportional to its mass and the rate at which its speed changes.

## How do I determine the mass of a vehicle for push force calculations?

The mass of a vehicle can be determined by taking its weight in kilograms and dividing it by the acceleration due to gravity (9.8 m/s²). This will give you the mass in kilograms.

## What is the maximum push force a vehicle can withstand?

The maximum push force a vehicle can withstand depends on various factors such as its weight, structural integrity, and the type of surface it is on. It is important to follow the manufacturer's guidelines and not exceed the recommended maximum push force.

## How does the surface of the road affect push force calculations?

The surface of the road can greatly impact push force calculations. A vehicle on a rough or uneven surface will experience more friction and resistance, requiring a higher push force to move it. On the other hand, a smooth and level surface will result in less resistance and a lower required push force.

## Can push force calculations be used for all types of vehicles?

Push force calculations can be used for most vehicles, but the results may vary depending on the type of vehicle and its design. Vehicles with larger surface areas or those with more weight distributed on their front or rear may require different calculations for push force.
