A horizontal force of 15 N pulls a block of mass 3.9 kg across a level floor.
Question:
A horizontal force of 15 N pulls a block of mass 3.9 kg across a level floor. The coefficient of kinetic friction between the block and the floor is μK = 0.25. If the block begins with a speed of 8.0 m/s and is pulled for a distance of 12 m, what is the final speed of the block?
Step by Step Answer:
Apply the workenergy theorem Newtons second law and the concept of kinetic friction See Figure Ans61...View the full answer

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
