Salim has a paper route. In the winter time, he puts his newspapers on a toboggan to pull them through the snow. The combined mass of the papers and the toboggan is 24 kg. The coefficient of static friction between the toboggan and the snow is 0.18. The coefficient of kinetic friction between the toboggan and the snow is 0.10.
a. With how much force must Salim pull in order to get the toboggan to start moving?
b. How much force is needed to keep the toboggan moving at a constant speed? Please can I get a step by step solution and answer
Well it does not say what angle he pulls at so I will assume it is horizontal straight ahead.
the force against the snow is the weight , m g
therefore the friction force is
mu m g
which is
0.18 * 24 * 9.81 Newtons
once you get started mu is less so
0.10 * 24 * 9.81 Newtons
(all on earth where g is about 9.81 meters / second^2)
