A physics student pulls a block of mass m = 22 kg up an incline
at a slow constant velocity for a distance of d = 4.5 m. The
incline makes an angle ? = 32° with the horizontal. The coefficient
of kinetic friction between the block and the inclined plane is µk
= 0.3.

A mass M slides upward along a rough plane surface inclined at angle = 0.16 in radians to the horizontal. Initially the mass has a speed Vo = 2.68 m/s, before it slides a distance L = 1.0 m up the incline. After sliding this distance the new speed of the mass is V /4 measured in m/s. What is the acceleration of the sliding mass? (Positive denotes acceleration up the incline; negative denotes acceleration down the incline.)

A crate slides down an incline plane of length L starting from rest. The plane makes an angle θ with the horizontal. What is the speed of the crate at the bottom of the plane? V=√2glsinθ
A rod of length L and negligible mass is attached to a uniform disk of mass M and radius R (see figure below).
A rod of length L and negligible mass is attached to a uniform disk of mass M and radius R (see figure below). A string is wrapped around the disk, and you pull on the string with a constant force F. Two small balls each of mass m slide along the rod with negligible friction. The apparatus starts from rest, and when the center of the disk has moved a distance d, a length of strings has come off the...

2. A uniform, solid cylinder with mass M and radius 2R is on an incline plane with angle of inclination of 6. A string is attached by a yoke to a frictionless axle through the center of the cylinder so that the cylinder can rotate about the axle. The string runs over a disk-shaped pulley with mass M and radius R that is mounted on a frictionless axle through its center. A block of mass M is suspended from the...
