Question

Find the acceleration of an 800-kg car that has a net force of 4,000 N acting upon it.

Answer 1

The acceleration of an 800-kg car with a net force of 4,000 N acting on it can be found using Newton's second law of motion. By dividing the net force by the car's mass, the acceleration is calculated to be 5 m/s².

Step-by-step explanation:

To find the acceleration of an 800-kg car with a net force of 4,000 N acting upon it, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma). Therefore, to find the acceleration (a), we divide the net force (F) by the mass (m).

Using the formula:

a = F / m

Where:

• F is the net force = 4,000 N
• m is the mass of the car = 800 kg

We get:

a = 4,000 N / 800 kg

a = 5 m/s²

The acceleration of the car is therefore 5 m/s².

Answer 2

The acceleration of the car is 5m/s²

Step-by-step explanation:

Given data

Force F= 4,000N

Mass of car m= 800kg

Acceleration a= ?

Applying the Newton's second law of motion which states that the rate of change of momentum of a body is proportional to the external force and takes place in the direction of the force

F=ma

a= F/m

a= 4000/800

a=5m/s²
