Question: problem 1 a crate with a mass of 80kg is...

Question details

Problem 1 A crate with a mass of 80kg is subjected to the two forces (as shown below) Initially, the box is moving at a velocity of 0.5 m/s to the right and then slides a distance of 2 m. The coefficient of kinetic friction between the crate and the horizontal surface is uk 0.2 800 N 80 K 400 N 30 D 2 M a) Draw the free-body diagram and clearly label all axes (10 pts) 8//o b) Write out the equations of motion and determine the normal force, Nb (15 pts) 2. c) What is the work of the 400N force? What is the work of the 800N force? What is the work of the frictional force? What is the work done by the weight? (15 pts) d) Set up the Work-Energy Equation. Using this equation, determine the velocity at 2m (10 pts) o lo
