Foundations of Motion and Kinematics

Let's calculate the acceleration of a car and the force required.

A car starts from rest (0 m/s) and reaches a speed of 20 m/s in 4 seconds. The car has a mass of 1200 kg.

  1. Calculate the acceleration:
    Initial velocity = 0 m/s
    Final velocity = 20 m/s
    Time = 4 s
    Acceleration = (20 m/s - 0 m/s) / 4 s = 20 m/s / 4 s = 5 m/s²

  2. Calculate the force needed to cause this acceleration:
    Mass = 1200 kg
    Acceleration = 5 m/s²
    Force = Mass × Acceleration = 1200 kg × 5 m/s² = 6000 Newtons (N)
