an object of mass 5.0 kilograms initially travelling
at12.0m/s horizentally enters a region where there is a
coefficientof Kinetic friction of 0.27
a) Use the concepts of work and energy to determine
thespeed of the mass after it has traveled 3 meters.
b) the mass now continues its motion by sliding up a
35degree incline.How far up the incline will it travel before
comingto rest? the coefficient of friction between the mass and
theincline is 0.20.
c) Now solve the same problems in a and b
usingNewton's laws- force mass, and acceleration.
