Circular motion, vertical surface with kinetic friction: A small block of mass 2.0 kg slides on a horizontal frictionless surface as it travels around the inside of a hoop of radius R 0.50 m. A view from above is shown. The coefficient of friction between the block and the hoop wall is 0.20. Therefore, the block is slowing down. a) Draw a free body diagram for the block in the position shown (you do not need to include forces perpendicular...
QUESTION 5 A mass of 12 kg is placed on a horizontal surface with friction with a coefficient of static friction of 0.81 and coefficient of kinetic friction of 0.44. A force of 13 Newtons is applied in the -y direction and a force of 16 Newtons is also applied in the -y direction. Another force is applied in the +x direction (see sketch). The force applied in the +x direction is increased until it is 1.9 times the force...
A block is resting on a horizontal surface. The mass of the block is 40 kg. The coefficient of static friction between the block and the surface is us = 0.3 and the coefficient of kinetic friction is uk = 0.20. A man then decides to push on the block with 30 newtons of horizontal force. a) What is the acceleration of the block? Explain. b) Suppose the man pushes on the block with 200 newtons instead. What is the...

A block of mass 0.528 kg slides with uniform velocity of 3.60 m/s on a horizontal frictionless surface. At some point, it strikes a horizontal spring in equilibrium. If the spring constant is k = 26.1 N/m, by how much will the spring be compressed by the time the block comes to rest? b. What is the amount of compression if the surface is rough under the spring, with coefficient of kinetic friction µk = 0.411?
