A working student works at a pub during weekends. The assigned task to him is to fill drinks for customers. He fills the pitcher full of Iced Tea, places it on the counter top and gives the 2.4kg pitcher a 8.2N forward push over a distance of 50cm to send it to a customer at the end of the counter. The coefficient of friction between the pitcher and the counter top is 0.15. a. What is the work done upon the pitcher by both the working student and the friction? b. Determine the kinetic energy of the pitcher after the working student pushed it. c. Find the speed of the pitcher after the force was applied.
