### Educational Analysis: Work and Friction on a Rough Surface**Figure Explanation:**The diagram illustrates a box of mass \( m = 54.0 \, \text{kg} \) being pushed across a rough surface. The box initially at rest is moved a distance \( d = 60.0 \, \text{m} \) by an applied force \( F_A = 240 \, \text{N} \) which acts at an angle of \( 30.0^\circ \) below the horizontal. The coefficient of kinetic friction between the floor and the box is \( 0.100 \).**Tasks and Solutions:**(a) **Work Done by the Applied Force** \[ W_A = 12470 \, \text{J} \](b) **Work Done by the Force of Gravity** \[ W_g = 0 \, \text{J} \](c) **Work Done by the Normal Force** \[ W_N = 0 \, \text{J} \](d) **Work Done by the Force of Friction** \[ W_F = 680 \, \text{J} \] *Note: Carefully consider the direction of the force of friction relative to the displacement.*(e) **Calculate the Net Work on the Box** Calculate the total work by summing up the individual works: \[ W_\text{Net} = \boxed{86} \, \text{J} \] *This value is incorrect. Re-evaluate the forces and their effects to determine the accurate net work.*(f) **Net Work through Net Force** Find the net force on the box and use it to calculate the work done: \[ W_\text{Net} = \boxed{0} \] *Review a diagram showing forces and their components to verify the net work calculation.***Important Concepts:**- The work done by gravity and normal force is zero because these forces act perpendicular to the displacement.- Friction opposes motion; its work calculation must incorporate direction and magnitude adjustments.- The angle of applied force affects the calculation of work done by that force.Ensure you understand vector components, particularly how they influence work done by forces at angles.

You have devised an experiment to measure the kinetic coefficient of friction between a ramp and a mass. You place the mass on the ramp at an angle high enough that the mass starts sliding. You measure the time it takes to fall down a known distance. The time it takes to fall down the 45 degree ramp starting from a standstill is At = 0.46 sec, m=1 kg, and the distance it falls, Ax , is 0.5 m. What is µk? m Дх in At Uk
