A car accelerates from rest at a rate of 2 m/s². What is the net force acting on the car if its mass is 1000 kg?
Correct Answer: 2000 N
Step 1: Identify the formula to use. We will use the formula F = ma, where F is the net force, m is the mass, and a is the acceleration.
Step 2: Write down the values given in the problem. The mass (m) of the car is 1000 kg and the acceleration (a) is 2 m/s².
Step 3: Plug the values into the formula. Replace m with 1000 kg and a with 2 m/s² in the formula F = ma.
Step 4: Calculate the net force. Multiply 1000 kg by 2 m/s² to get F = 2000 N.
Step 5: State the final answer. The net force acting on the car is 2000 N.
Newton's Second Law of Motion – This law states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma).
