A 35 kg sled slides along a horizontal surface on which the coefficient of kinetic friction is 0.25. Its velocity at point A is 10.0 m/s, and its velocity at point B is 2.0 m/s. You must use Work/Energy methods (not Kinematics).(a) What is the frictional force acting on the sled?(b) How much work is done on the sled by friction over the displacement ∆x = xB − xA?(c) What is the distance the sled travels between A and B? ### Motion of a Block on a Horizontal SurfaceThe diagram illustrates a block of mass \( m \) moving on a horizontal surface. The forces acting on the block and its displacement are represented as follows:1. **Forces Acting on the Block:** - **Normal Force (\( F_N \))**: This is the force exerted by the surface on the block in the upward direction, perpendicular to the surface. - **Gravitational Force (\( F_g \))**: This is the force exerted by the Earth on the block in the downward direction, equal to the weight of the block \( (mg) \). - **Kinetic Friction Force (\( f_k \))**: This is the force exerted by the surface on the block opposing its motion, pointing to the left.2. **Displacement (\( \Delta x \))**: - The block moves from point \( A \) to point \( B \) on the horizontal surface. - \( \Delta x \) is the vector representing the displacement from \( A \) to \( B \), where \( \Delta x \) is the distance traveled in a direction parallel to the surface.The diagram uses arrows to indicate the direction of these forces and displacement:- The normal force \( F_N \) is shown as an upward arrow.- The gravitational force \( F_g \) is shown as a downward arrow.- The kinetic friction force \( f_k \) is shown as an arrow pointing to the left.- The displacement \( \Delta x \) is represented by a red arrow pointing to the right from point \( A \) to point \( B \).This diagram helps in understanding the dynamics of the block moving on a horizontal surface and how different forces interact during its motion.
