The figure above shows an object (blue) on top of a wedge (gray) sitting on a scale (black). When the object is released, is slides down the slope of the wedge. What is the normal force of the scale on the wedge (this is the force the scale will read) as the mass slides down the slope?
There is friction between the object and the wedge and between the wedge and the scale. The static friction between the wedge and the scale is large enough to keep the wedge from moving.
The mass of the object is 2.4 kg.
The mass of the wedge is 6.0 kg.
The angle of the wedge is 16 degrees.
The coefficient of kinetic friction between the object and wedge is 0.13.
Give your answer in Newtons and to three significant digits.

(Figure 1)shows a 250 g hamster sitting on an 750 g wedge-shaped
block. The block, in turn, rests on a spring scale. An extra-fine
lubricating oil having μs=μk=0 is sprayed on the top surface of the
block, causing the hamster to slide down. Friction between the
block and the scale is large enough that the block does
not slip on the scale.

An object of mass m is at rest at the top of a smooth slope of height h and length L. The coefficient of kinetic friction between the object and the surface, μk, is small enough that the object will slide down the slope if given a very small push to get it started.Sam, whose mass is 75 kg , stands at the top of a 14-m-high, 90-m-long snow-covered slope.

A 200g hamster is sitting on a 800g wedge-shaped block. The block, in turn, rests on a spring scale.a) Initially, static friction is sufficient to keep the hamster from moving. In this case, the hamster and the block are effectively a single 1000g mass and the scaleshould read 9.8N. Show that this is the case by treating the hamster and the block as separate objects and analyzing forces.b) An extra fine lubricating oil having µs= µk= 0 is sprayed on...

An object with a mass, m = 5 kg, is released from rest at the top of the ramp. The length of the ramp is 2.3 m. The object slides down the ramp reaching a speed of 2.1 m/s at the bottom. a) If the friction force between the ramp and the object is 3 N, find the angle between the ramp and the horizontal theta (in degrees). b) What speed (in m/s) does the object reach at the bottom...

You have a truck at the top of a boat ramp and it has a rope that is tied to the trailer down the ramp. The boat is just sitting on the trailer with nothing but friction to keep it in place. Air Drag is zero. What you know is: Mass of Boat = 100 kg Mass of Trailer = 280 kg Mass of Truck = 2150 kg Angle of ramp = 5 degrees Coefficent of Static Friction, Boat on...

Two masses are connected by a massless rope. The mass of object 1 is 5.5 kg, and it rests on a surface with a 1.7 coefficient for static friction (us) and a .90 coefficient for kinetic friction (uk). Object 2 has a mass of 8.3 kg and hangs over the edge of the surface by a frictionless, massless pulley. The two objects begin at rest when object 2 is released to hang freely. A.) Draw a free body diagram for...
