A block weighing 14 lb is placed on an incline plane and
connected to a 10 lb block, as shown in the diagram. The pulley is
frictionless. The coefficient of friction between block and plane
is 1/7. For what two values of angle ? will the
system move with constant velocity?
(Hint: You need the identity relating sin? and cos?; find the
angles when block is sliding down and up)

The 190-lb carriage has an initial velocity of 10.3 ft/sec down
the incline at A, when a constant force of 65 lb is
applied to the hoisting cable as shown. Calculate the velocity of
the carriage when it reaches B. Show that in the absence
of friction this velocity is independent of whether the initial
velocity of the carriage at A was up or down the
incline.

340-lb carriage has an initial velocity of 6.3 ft/sec down the
incline at A, when a constant force of 120 lb is applied to the
hoisting cable as shown. Calculate the velocity of the carriage
when it reaches B. Show that in the absence of friction this
velocity is independent of whether the initial velocity of the
carriage at A was up or down the incline.

A solid sphere of radius R and mass 10.0kg is placed on an incline plane of variable angle. The coefficients of static and kinetic friction are μs=0.29 and μk=0.14. (a) What is the minimum angle such that the sphere slides down the plane? o (b) What is the frictional force at this angle? N (c) If the angle of the incline plane is half of that in part (a) what are the acceleration of the sphere and the force of...

A block of mass m is placed in a smooth-bored spring gun at the bottom of an inclined plane
A block of mass m is placed in a smooth-bored spring gun at the bottom of an inclined plane, such that it compresses the spring by an amount xc, as shown in the figure below. The spring has a spring constant k. The incline makes an angle θ with the horizontal and the coefficient of friction between the block and the inclined plane is μ. The block is released, exits the muzzle of the gun, and slides up the incline...
