An automobile with a mass of 1000 kg accelerates at a traffic light with a force of 4000 N. What is the automobile's acceleration?

Explanation:

Given

mass (m) = 1000 kg

Force (F) = 4000 N

Acceleration (a) = ?

We have the relation

F = m * a

or, 4000 = 1000 * a

or a = 4000 / 1000

a = 4 m/s²

The acceleration of the automobile is 4 m/s²

Hope it will help :)❤

Explanation:

According to Newton's Second Law of Motion, force is equal to the product of mass and acceleration.

We know the mass is 1000 kilograms and the force is 4000 Newtons. Let's convert the units to simplify the question for later.

Substitute the values into the formula.

We want to find the acceleration, a. We must isolate the variable on one side of the equation.

1000 kg and a are being multiplied. The inverse operatio of multiplication is division. Divide both sides of the equation by 1000 kg.

The kilograms will cancel.

The autombile's acceleration is 4 meters per square second.

if i write it on a piece of paper and submit it to you would that be okay
