Question

What force in Newton is required to accelerate a car starting from rest to 20 m/s in 15 seconds if the mass of the car is 2500 kilograms?

Answer 1

We will solve this question using the second law of motion which states that force is directly equal to the product of mass and acceleration.

$\sf \: F=ma$

Where,

• F is force
• m is mass
• a is acceleration

In our case,

• F = ?
• m = 2500 kg
• a = 20m/s

$\tt \: F_{net} = 2500 \times 20 \\ \tt= 50000$

Thus, The force of 50000 Newton is required to accelerate a car of 2500 kg...~

Answer 2

Answer:

Explanation:

f =ma

F 2500 kg (20m/s-0m/s/15s)

F=2500kg(1.33m/s²)

F =3,325 N
