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?

Consider the small cube of mass m in the figure. It
slides down a circular path of radius R carved into a
large block of mass M. M rests on a table, and
both blocks move without friction (i.e. M can easily slide
sideways). The blocks are initially at rest, and m starts
from the top of the path.
Find the velocity of m as it leaves the block.

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...

A solid block of mass 60.0 kg starts from rest and slides down a rough surface with a length of 10.0 m where the coefficient of friction is uk=0.20. The surface is inclined at 40.0°. After sliding 10 meters down the incline it hits a spring with a spring constant of ks = 550.0 N/m. Draw a freebody Diagram indicating all forces. Write out and solve the force and energy equations. How high is the block above the spring at...

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 5kg block starts at a height of 10m above the ground and slides 20m down a rough surfaced incline. The work done by the frictional force in sliding down the incline is 240 J. It reaches the bottom of the incline and then enters a frictionless vertical loop of radius 2m. The speed of the block at the bottom of the hoop is 10.0m/s. The block performs one revolution and exits the loop.o sinu or mohe imImtombnes biduo nsotinpie...

A box starts to slide down from a rough inclined plane at an initial height of h = 2.1 m as shown below. The box starts sliding from rest (the initial speed is zero) and reaches the bottom of the plane at a final speed of 3.3 m/s. The inclination angle is 0 = 11°. Find the friction coefficient p between the box and the plane by following the steps listed below. g V.=0 а IIIIIIII M...

A small block with mass 0.0375 kg slides in a vertical circle of radius 0.600 m on the inside of a circular track. During one of the revolutions of the block, when the block is at the bottom of its path, point A, the magnitude of the normal force exerted on the block by the track has magnitude 4.05 N . In this same revolution, when the block reaches the top of its path, point B, the magnitude of the...
