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...

A 2.74 kg block is pushed 1.41 m up a vertical wall with a
constant speed by a constant force of magnitude F applied at an
angle of 66.3 with the horizontal. The acceleration of gravity is
9.8 m/s2. If the coefficient of kinetic friction between the block
and wall 0.415, find the work done by F.

A large rough ramp is inclined φ=35 degrees above the horizontal. A block of mass m = 5 kg is sliding on the board and the coefficient of kinetic friction between the block and the ramp is μk=0.3 . The block is tied to a string of length L = 0.25 meters so that the block moves about a circular trajectory. HINT: I'd recommend drawing the FBDs from a side-view. a) Draw a complete FBD of the block at the...

A small block with mass 0.0475 kg slides in a vertical circle of radius 0.0730 m on the inside of a circular track. There is no friction between the track and the block. At the bottom of the block's path, the normal force the track exerts on the block has magnitude 3.70 N. What is the magnitude of the normal force that the track exerts on the block when it is at the top of its path?

A 2.00-kg block is tied to a wall and placed on top of a 5.00-kg block, as shown. A horizontal force of 55.0 N is applied to the 5.00-kg block. There is a coefficient of kinetic friction of 0.250 between all moving surfaces. Determine (a) the tension in the string and (b) the acceleration of the 5.00-kg block. ANSWER IS: a) 4.90 N; (b) –6.59 m/s2
