The coefficient of static friction (μ) between the sole of a basketball shoe and a basketball court surface is 0.64. If point guard Ken wears this shoe when he plays basketball and he pushes down on the surface when he starts to run with a vertical force of 1,784.6 N, then what is the maximum horizontal force (Fh, in N) he can apply to the surface without slipping when he begins running? Include units in your answer.
Fn = normal force by the surface = 1784.6 N
μ = Coefficient of friction = 0.64
maximum horizontal force = frictional force = f = μ Fn = 0.64 x 1784.6 = 1142.14

The coefficient of friction between a basketball shoe and the stave is 0.56, and the normal reaction force acting on the shoe is 350 N. How much force does it require to make the shoe slip?
You are trying to determine the coefficient of static friction between your shoe and the floor. To do so, you place your shoe on the ground, attach a spring scale, then pull horizontally on the shoe until it just barely starts to move. You take note of the spring scale reading at that moment. Then you put some known extra masses into your shoe and repeat the process several times. (a) What is the purpose of adding extra masses and...
An 85 kg box rests on a horizontal surface. The coefficient of static friction between the box and the surface is 0.50. A horizontal force 250 N force is applied to the box. What is the magnitude of the static friction force on the box? A.42N B.250N C.16.5N D.130N E.0.00N
Determine the minimum coefficient of static friction between the disk and the surface so that the disk will roll without slipping. Neglect the mass of the pulleys. Take the touching point of the disk and the surface as IC and work from there. For the disk,
- A 3.1-kg flower pot sits on the ground. The coefficient of static friction between the flower pot and the ground is 0.54. 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?
A vase was placed on the coffee table. The coefficient of static friction between the vase and the table is 0.4176, whereas the coefficient of kinetic friction is 0.2082. The vase weighs 1.29667kg. A cat decided to redecorate the room by pushing the vase off the table. As the cat pushes the vase with its paw, the vase moves. Then, the cat maintains a constant applied force of 8.904N on the vase in the positive x-direction. What is the acceleration...
A vase was placed on the coffee table. The coefficient of static friction between the vase and the table is 0.4437, whereas the coefficient of kinetic friction is 0.1331. The vase weighs 1.0978kg. A cat decided to redecorate the room by pushing the vase off the table. As the cat pushes the vase with its paw, the vase moves. Then, the cat maintains a constant applied force of 7.278N on the vase in the positive x-direction. What is the acceleration...
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
A block of mass m lies on a horizontal table. The coefficient of static friction between the block and the table is ?s. The coefficient of kinetic friction is ?k, with ?k<?s. 1)If the block is at rest (and the only forces acting on the block are the force due to gravity and the normal force from the table), what is the magnitude of the force due to friction? 2)Suppose you want to move the block, but you want to...
