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?
Question 12 8 pts Block A rests on the ground and the coefficient of static friction between the ground and Block A is 0.20. If the weight of the suspended cylinder D is 5 lb, determine the minimum weight of Block A (in pounds) so that it does not tip. Neglect any friction at pulley C. Round to the nearest whole pound. Hint 1: Break the tension force from the rope into component forces. Hint 2: It might help to...
The tractor has a weight of
4500 lb with center of gravity at G. The driving traction is
developed at the rear wheels B, while the front wheels at A are
free to roll. If the coefficient of static friction between the
wheels at B and the ground is s = 0.5 possible to pull at P = 1200
lb without wheels at B to slip or the front wheels the ground.

What is the coefficient of the static friction between the
coin and the turntable?
010 10.0 points A coin is placed 27 cm from the center of a horizontal turntable, initially at rest. The turntable then begins to rotate. When the speed of the coin is 130 cm/s (rotating at a constant rate), the coin just begins to slip. The acceleration of gravity is 980 cm/s What is the coefficient of static friction be
