Question

1. what force is needed to accelerate a 1,000 kg car at 3 m/s²?

3,000 n
2,000 n
1,000 n
4,000 n

Explanation:

Step1: Recall Newton's Second Law

Newton's second law of motion states that the force \( F \) acting on an object is equal to the mass \( m \) of the object multiplied by its acceleration \( a \), i.e., \( F = m \times a \).

Step2: Identify given values

The mass \( m \) of the car is \( 1000 \, \text{kg} \) and the acceleration \( a \) is \( 3 \, \text{m/s}^2 \).

Step3: Calculate the force

Substitute the given values into the formula: \( F = 1000 \, \text{kg} \times 3 \, \text{m/s}^2 = 3000 \, \text{N} \).

Answer:

A. 3,000 N
