5. A small mass m starts from rest and slides from the top of a fixed sphere of radius r. (a) If the sphere is frictionless, at what angle θ from the vertical does the mass leave the surface? (b) Suppose there is friction between the mass and the sphere with friction coefficient =0.1. What is the minimum angle θmin at which the mass will start to slide along the sphere? (c) The mass is now placed just past this...
A block of mass m starts from rest and slides down from the top of a wedge of height h and length d. The surface of the wedge forms an angle of ? with respect to the horizontal direction. The force of kinetic friction between the block and the wedge is f. How fast is the block traveling when it reaches the bottom of the wedge?
A block of mass m is initially at rest at the top of an inclined plane, which has a height of 6.2 m and makes an angle of θ = 22° with respect to the horizontal. After being released, it is observed to be traveling at v = 0.65 m/s a distance d after the end of the inclined plane as shown. The coefficient of kinetic friction between the block and the plane is μp = 0.1, and the coefficient...
As shown below (not to scale), a block of mass starts from rest
and slides down a frictionless ramp of height h. Upon reaching the
bottom of the ramp, it continues to slide across a flat
frictionless surface. It then crosses a "rough patch" on the
surface of length d=10m. This rough patch has a coefficient of
kinetic friction uK=.1. After crossing the rough patch, the block's
final speed is vf=2m/s. What is the height of the ramp? Hint: I...
