Hey wyd what do you want me to bring in

When the block of mass is sliding down on an inclined plane in the classroom. The angle at which it falls will determine the type of speed at which it falls.  

  • The kinetic friction among the block and the surface of the inclined plane is equal to the tangent of the angle that will be formed with the ground. Hence the mass of the block will be constant.

Hence the option A is correct.
