Question

How much net force is required to accelerate a 1000 kg car at 4.00 m/s2?​

Answer 1

Answer:

4000 N is the required net force.

Explanation:

Given:

• acceleration (a) = 4.00 m/s²
• mass (m) = 1000 kg

To find:

Net force required to accelerate the car.

Solution:

Force is defined as the push or pull on an object by interacting with one or more other objects by the means of pushing or pulling.

Net force is defined as the overall force on an object after all the forces are added together.

Now according to Newton's second law,

F = m*a

• where F is force
• m is mass and
• a is acceleration.

By using this formula we will find the required net force.

F = m*a

Now by substituting the values, we get

→ F = m*a

→ F = 1000 × 4

= 4000 N

Answer 2

$\bigstar$ Given

Mass = 1000 kg

Acceleration = 4.00 m/s²

$\bigstar$ To Find

Force

$\bigstar$ Solution

We know that

$\red{\sf \longrightarrow F=ma}$

Here

• F = Force
• m = Mass
• A = Acceleration

Units

• F = Newton (N)
• m = kilogram (kg)
• a = metre/second squared (m/s²)

According to the question

We are asked to find force

Therefore

We must find "F"

Given that

Mass = 1000 kg

Acceleration = 4.00 m/s²

Hence

• m = 1000 kg
• a = 4 m/s²

Substituting the values

We get

$\pink{\sf \longrightarrow F=1000 \times 4 \ N}$

Therefore

$\purple{\sf \longrightarrow F=4000 \ N}$

Hence

$\checkmark$ Force = 4000 N
