A 60 kg man wishes to run on ice. The coefficient of static friction between his shoes and the ice is .1. What is the maximum possible acceleration?
Maxmimum static friction = 0.1*60*9.8
Now the friction force is the force which will push him forwards
else he will just slide.
So
F = 0.1*60*9.8
We know
F = ma
60*a = 0.1*60*9.8
a = 0.98 m/s^2

The 75-kg man pushes on the 150 kg crate with a horizontal force F The coefficients of static and kinetic friction between the crate and the surface are us=0.3 and uk = 0.18, and the coefficient of static friction between the man's shoes and the surface is u's=0.8. (Figure 1) What is the greatest acceleration the man can give the crate if the man's acceleration is zero at this instant? (Ctri)

Maria pushes the flower pot with a force of 5.2 Newtons, but it does not move. How strong is the static friction? -A 1.6-kg book sits on a table. The coefficient of static friction between the book and the table is 0.39. What is the hardest you can push on the book without it moving?
An 1 kg toaster is not plugged in. The coefficient of static friction between the toaster and a horizontal counter-top is 0.3. To make the toaster star moving, you carefully pull on its electric cord. For the cord tension to be as small as possible, you should pull at what angle above the horizontal? State your answer to the nearest tenth of a degree.

Application of Newtons Laws: Two skaters, a man and a woman, are standing on ice. Neglect any friction between the skate blades and the ice. The mass of the man is 82 kg and the mass of the woman is 48 kg. The woman pushes on the man with a force of 45 N due east. Determine the acceleration (magnitude and direction) of a) the man b) the woman the mass
The coefficient of friction between a 0.17 kg puck and and the ice is μk = 0.15. If the puck leaves a hockey stick traveling at 20 m/s, what is its speed when it reaches the goalie 15 m away? How much time does the goalie have to react? Assume the puck travels on the ice the whole time.
