1.0 kg block, a = 6 m/s². Applied force?

Question

1.0 kg block, a = 6 m/s². Applied force??  
A. 0 N  
B. 3 N  
C. 6 N  
D. Cannot determine

Accepted Answer

Correct Answer: (C)6 N. 
Rationale: The applied force on the block is 6 newtons.Newton’s Second Law of Motion states that the net force acting on an object is equal to the product of its mass and its acceleration. The relationship used is:force equals mass multiplied by accelerationwhere force is the applied force, mass is the mass of the object, and acceleration is the rate of change of velocity. With a mass of 1.0 kg and an acceleration of 6 meters per second squared, the force can be calculated directly.A) 0 NA force of zero would result in no acceleration. Since the block is accelerating at 6 meters per second squared, a nonzero force must be acting on it.B) 3 NThis value is half of the correct force and would correspond to either a smaller acceleration or a smaller mass. It does not satisfy the given conditions.C) 6 NApplying Newton’s Second Law gives:force equals 1.0 kilogram multiplied by 6 meters per second squaredforce equals 6 newtonsThis correctly matches the given mass and acceleration.D) Cannot determineAll necessary information, mass and acceleration, is provided, so the applied force can be determined.ConclusionUsing Newton’s Second Law, the applied force required to produce an acceleration of 6 meters per second squared on a 1.0 kg block is 6 newtons.
