A man drags a 50 kg sack of rice across a smooth floor, if the sack of rice accelerates at 40m/s². How much force does the man exert in dragging it?​

Answer:

Here's how to solve this problem using Newton's Second Law of Motion:

Understanding the Concepts

Newton's Second Law: This law states that the force acting on an object is equal to its mass times its acceleration (F = ma).

Force: A push or pull that can cause a change in an object's motion.

Mass: The amount of matter in an object.

Acceleration: The rate of change of velocity.

Calculations

Identify the given values:

Mass (m) = 50 kg

Acceleration (a) = 40 m/s²

Apply Newton's Second Law:

Force (F) = m * a

F = 50 kg * 40 m/s²

F = 2000 N (Newtons)

Answer: The man exerts a force of 2000 Newtons in dragging the sack of rice.
