What is the coefficient of kinetic friction between the block and the horizontal surface?

0.2
The coefficient of friction between the block and the horizontal surface is 0. 2.

How do you find the frictional force between a block and a surface?

As the lower block receives a force $F = 15{\text{N}}$ to slide, the force of friction $f$ will try to oppose the sliding. Hence the total force acting on the lower block in the horizontal direction will be $F – f$ . Thus the frictional force between the blocks will be $f = 5{\text{N}}$ . So the correct option is C.

What is the magnitude of the frictional force on the block?

The component of the net force perpendicular to the slope must be zero. The bormal force must cancel the perpendicular component of gravity. Therefore the magnitude of the normal force n = mg cosθ. The magnitude of the frictional force is proportional to the normal force, fk = μkmg cosθ.

What is the coefficient of kinetic friction between the block and the floor?

The co-efficient of kinetic friction, μk , between the floor and the block is 0.2.

How do you find the magnitude of the static frictional force?

The static friction value ranges between zero and the smallest force which needs to start the motion. The formula to calculate the static friction is given as: Static Friction = Normal Force x Static Friction coefficient. Static friction = 60 N.

What is formula of mass?

Mass is defined as the amount of matter present in a body. The SI unit of mass is the kilogram (kg). The formula of mass can be written as: Mass = Density × Volume.

Where does top block land when pulled?

The top block will land directly below where it starts because objects at rest tend to stay at rest. The top block will land to the left of where it starts because of the static friction between the blocks. The top block will land to the left of where it starts because of the kinetic friction between the blocks.

How do you find the friction between a block and surface?

There will be kinetic friction between the surface and the block since it is in motion. The kinetic friction will be equal to μ k * m1 * g This formula for tension is consistent with general observation, as the tension has to be equal to the applied force which here is the force applied plus the frictional force.

What happens to static friction when a block is pulled?

If the force applied on the block is less than the limiting friction, then static friction will act on the blocks, and the blocks will be at rest. A block of mass m1 is pulled with acceleration a.

How much force does it take to move a 5 kg block?

A force F is exerted on a 5 kg block to move it across a rough surface, as shown above. The magnitude of the force is initially 5 N, and the block moves at a constant velocity. While the block is moving, the force is instantaneously increased to 12 N.

What is the kinetic friction between a block and a rope?

A block of mass m1 is pulled with acceleration a. There is a tension T developed in the rope. There will be kinetic friction between the surface and the block since it is in motion. The kinetic friction will be equal to μ k * m1 * g
