A block is placed on a plane that is inclined at 30 o to the horizontal. The coefficients of static and kinetic friction for the block on the inclined plane are 0.5 and 0.4, respectively. The block a accelerates down the inclined plane. b travels down the inclined plane at constant velocity. c travels up the inclined plane at constant velocity. d remains stationary on the inclined plane.

A box placed on a inclined surface is held at rest by a rope (see figure). There is friction between the box and the surface. If the box has mass 5.4 kg, the ramp angle is 29.3 degrees, and the coefficients of friction are μ S = 0.39 and μ k = 0.28, then calculate the magnitude of the friction force (in N). +y +х We were unable to transcribe this imageWe were unable to transcribe this image

Two uniform spheres of identical mass and radius are placed on
inclined planes at the same height h and inclination angle θ. One
plane is rough and causes one sphere to roll down the plane; the
other is frictionless, and so the sphere on it slides down the
incline.
(a) Find the ratio of the kinetic energies of the two spheres at
the bottom of the incline: .
(b) Find the ratio of their speeds at the base of the...

A block is at rest on an inclined plane (shown in diagram). Coefficients of friction are μ-02, μ,-0.17. Gravity is 9.8 m/s2 Okg What is the normal force on the box? Let's assume friction were not a factor-the box would slide down the ramp. What is the magnitude of the force that causes the box to24 down the ramp? What is the static friction force on the box? Will the box slide without being pushed down the ramp? What is...
