Understanding the Concepts
* Force: A push or pull that can change the motion of an object. (Measured in Newtons, N)
* Mass: The amount of matter in an object. (Measured in kilograms, kg)
* Acceleration: The rate at which an object's velocity changes. (Measured in meters per second squared, m/s²)
* Newton's Second Law of Motion: This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The formula is: F = ma
Calculation
1. Identify the given information:
* Mass (m) = 2000 kg
* Force (F) = 4200 N
2. Rearrange the formula to solve for acceleration (a):
* a = F / m
3. Plug in the values and calculate:
* a = 4200 N / 2000 kg
* a = 2.1 m/s²
Answer: The acceleration of the truck is 2.1 m/s².
