1. A 10 kg at a mail facility slides down a 10 meter sorting chute. Theheight of the chute is 2 meters. The speed of the package at thetop of the chute is 5 m/s, and it is moving at 3 m/s when itreaches the bottom. Let g = 10 m/s?a. What is the change in the kinetic energy of the package whenit slides down the chute? Be careful with the sign (+/-)!M10 m2m9.8 mb. Determine whether the work done by gravity and the normal force on the package is positive, negative, or zero.Hint: Draw each force vector and displacement vector with their tails together. Think about angle between theforce and displacement.Gravity:Normal Force:c. What is the work done by gravity as the package slides down the chute? Be careful with the sign (+/-)d. How much mechanical energy became thermal energy during this process, i.e., what is AEherm? Use the work-energy relation with friction: AKE + AE,herm = Wext.e. What is the magnitude of the frictional force?f. What is the coefficient of kinetic friction between the package and the chute?

As per guidelines we are suppose to do only 3 subpart from multipart question. Please post the rest…
