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.
