A block of mass m pulled with constant velocity over a floor by a force T inclined at an angle theta with the floor. The coefficient of friction between the block and the floor in mu. It is a box on floor drawn by a cord half way down fron edge at an angle of about 30 degrees from horizontal. No actual dimensions. The magnitude of the vertical component of the force exerted on the block by the floor is:a. mgb. mg-T cos thetac. mg+T cos thetad. mg-T sin thetae. T sin theta

Answer :

The floor's force on the block, measured in terms of its vertical component, is expressed as follows: mg- t sin theta

What is the friction coefficient?

The resistive friction force (Fr) multiplied by the normal or horizontal force (N) forcing the objects together yields the coefficient of friction (fr), which is a numerical value. It can be represented by the equation fr = Fr/N.

What is a force?

A push or pull that an object experiences as a result of interacting with another item is known as a force. Every time two items interact, a force is exerted on each of the things. Newton(N) F=ma stands for the Si system of force.
