Asked by Hena
I need Help answering this question what equations do i use from Newton's Law and how to solve it. I Have a test on Wednesday and im lost please help.!!!
A piano is to be slid across the floor.IT had a mass of 450 kg.
A) Calculate the normal force supporting the piano.
B)If the coefficient of static friction between the floor and the piano is 0.35, calculate the minimum amount of force needed to get the piano to move.
C) ONce the piano is moving a horizontal force of 1.1X10^3 N is necessary to keep it moving at a constant speed. Determine the coefficient of kinetic friction.
